Use of "I", "we" and the passive voice in a scientific thesis [duplicate]

Possible Duplicate: Style Question: Use of “we” vs. “I” vs. passive voice in a dissertation

When the first person voice is used in scientific writing it is mostly used in the first person plural, as scientific papers almost always have more than one co-author, such as

We propose a new method to study cell differentiation in nematodes.

Often the "we" also includes the reader

We may see in Figure 4.2 that...

However, I am writing a thesis which means I am the only author and I even have to testify in writing that the work is my own and I did not receive any help other than from the indicated sources. Therefore it seems I should use "I", but this seems to be very unusual in scientific writing and even discouraged as one may sound pretentious or self-absorbed. However, the alternative is to use the passive voice, which seems to be even more discouraged as it produces hard to read writing and indeed an entire thesis in the passive voice may be indigestible for any reader.

So far, I used the second form of "we" extensively that includes me and the reader. This form is often natural when describing mathematical derivations as the truth is objective and it suggests that I am taking the reader by the hand and walking her through the process. Still, I'm trying not do overdo this form.

However, eventually I will need to refer to methods that I propose and choices that I have made. Should I just follow scientific convention and use "we" although it is factually inaccurate or indeed write in the scorned-upon "I"?

• 3 I find the use of "we" odd if there is only one author. I read a paper by a single author recently and he consistently wrote things like "we propose...", "we then present..." and I kept thinking, wait, who did you work with? –  Flash Commented May 10, 2011 at 14:08
• 2 @Andrew: Seriously? You read academic papers, and you're not at least aware of the convention? You might not endorse it, but you could just accept it as something some people do. –  FumbleFingers Commented May 10, 2011 at 22:05
• 1 @oceanhug: Probably saying nothing you don't already know, but bear in mind this sort of question could become a bit of a 'poll'. And there will be plenty of people who actively dislike using the effectively 'singular we' in any context. Because of associations with the 'academic old guard', the 'regal we', whatever. Or in solidarity with the march towards 'individualism' that marks Western civilisation. You, on the other hand, have a thesis to write. –  FumbleFingers Commented May 10, 2011 at 22:58
• I have seen academic papers by a single author using I . However I agree with FumbleFingers that most of the time you would use we , and that I sounds strange in an academic paper. Personally, if I were to read your thesis and saw we , I wouldn't find it as an implication that you were not the only author of the work. Also, I assume you will have a thesis supervisor, who is also responsible to check (and possibly approve) your work, so you can include him/her in the we . –  nico Commented May 11, 2011 at 6:47

I tried to use "I" in the first version of my thesis (in mathematics). When my advisor suggested corrections, the most detailed and strongly-worded of them was to use "we"; later, I asked another young professor whether one could use "I" and she said "Only if you want to sound like an arrogant bastard", and observed that only old people with established reputations can get away with it.

My extremely informal recollection of some articles that are more than, say, forty years old is that the singular is used more often, so what she says may be true but for a different reason than simple pride. The modern culture may disparage apparent displays of ego simply because of the greater prevalence of collaboration, whether or not your paper is a product of it. This is complete speculation, though.

I disagreed with the change at the time but acquiesced anyway, and now, with distance, I realize that it was a good idea. Scattering the paper with "I" draws attention to the author, and especially in mathematical writing, the prose is filled with impersonal subjects (that is, you often don't mean "I" literally, as in "If y = f(x), then we have an equation..."). Using "we" allows it to simply sink into the background, where it belongs. If it's your thesis, you don't have to put any special effort into reminding the reader who is talking, just like in an essay, they used to tell me not to say "in my opinion" before stating it.

EDIT: Oh, I forgot entirely about "the author". I hate that phrase, because it is just as inconsistent with "we" as with "I" and disingenuous to boot. If you have to make a truly personal remark, just say "I", and perhaps set off the entire comment by "Personally..." or something like that.

• 3 Excellent answer. I totally agree on all points, which you express well. Egalitarianism, individualism, or whatever may push for the first person singular, but it's distracting in serious academic texts. Though I don't have a big problem with ' the author ' once (maybe twice). –  FumbleFingers Commented May 10, 2011 at 22:14
• 7 We think you’ve hit the nail on the head with your speculation. –  Konrad Rudolph Commented May 11, 2011 at 14:23
• 1 -1; I strongly disagree. Moreover, the APA (and perhaps other) style manuals disagree. The persistence of using the passive voice to minimize the use of first person pronouns is a historical affectation that most of us have been trained from a young age to slavishly employ. However, it tends to yield awkward prose that is hard to read. If the greatest crime that must be committed is either "egotism" or "lack of clarity", I certainly choose to be egotistic. –  russellpierce Commented Oct 23, 2012 at 16:06
• 6 @RyanReich: You know that a down-vote is not a personal criticism right? –  russellpierce Commented Dec 24, 2012 at 14:45
• 2 @russellpierce. There are enough people around saying "never use passive voice" that they need to be argued against. The passive voice should be used whenever it improves your prose, and this happens moderately often. If you look at some early scientific papers, the incessant use of the first person pronoun can be really distracting, and many of these uses can be avoided using the passive voice. –  Peter Shor Commented Oct 16, 2017 at 16:00

I don't think there's anything wrong with using we in single-author scientific journal papers. It's the tradition, and if you use I in scientific papers it stands out, not necessarily in a good way. On the other hand, a PhD thesis is not a scientific journal paper, but a PhD thesis, and if you want to use I in it I don't see anything wrong with that.

The passive voice should not be used to avoid writing I or we . If the entire thesis is written in the passive voice, it is much harder to read, and the sentences within it 1 have to be reworded awkwardly so that some good transitions between the sentences within a paragraph are lost. On the other hand, if some sentences seem to require the passive voice, by all means those sentences should be written in the passive voice. But the passive voice should only be used where it is justified, that is, where its use improves readability of the thesis.

1 See how much better your sentences would read here.

• Shor: In the end I mostly go with @Ryan Reich's answer, but you and @Rafael Beraldo make additional important points. I'm minded to say that - probably with no concious effort on your part - you only used I once in your second paragraph. And that was only to quote the word. When I compare my sentences here with yours, I think yours look more authoritative, academic, educational, etc. You say you don't see anything wrong with I, but I bet you wouldn't use it in OP's position lol –  FumbleFingers Commented May 10, 2011 at 22:47
• 3 @FumbleFingers: The lack of pronouns I and you in my second paragraph was quite deliberate, and took some effort. –  Peter Shor Commented May 11, 2011 at 1:30
• Shor: Ah. Well, it was worth the effort from my point of view, if that's any recompense for your labours. But I notice you don't deny you'd avoid using I in a thesis yourself, even if you wouldn't think of that as particularly wrong on the part of someone else. –  FumbleFingers Commented May 11, 2011 at 2:40
• @FumbleFingers: I've only written one thesis, and the pronoun we is the one I mainly used in it. –  Peter Shor Commented May 11, 2011 at 10:30
• 1 some authors use I instead of we when only one author: link.springer.com/article/10.1007%2Fs00114-008-0435-3 –  Tomas Commented Apr 13, 2016 at 10:39

By all means write "I". By an amusing coincidence, I have in front of me the article Deformations of Symmetric Products , a proceedings article published by Princeton University Press. The author is the late George R. Kempf, a distinguished algebraic geometer, and on the very first page I read [not we read:-)]: "My proof uses heavily the deformation theory..." . And on the second page "I will use without particular references standard facts from deformation theory". I could give any number of examples: this usage is quite widespread.

• 1 The very example you give supports the opposite view. As a ' distinguished algebraic geometer ', of course Kempf could get away with "I" if he wanted to be self-indulgent. It may become less noticed in future, but in the here and now many (including perhaps those who will assess OP's thesis) both notice and deplore it. –  FumbleFingers Commented May 10, 2011 at 22:22
• 1 @FumbleFingers: I just gave a factual reference to show that "I" is indeed used. Calling the late George Kempf self-indulgent is rather insulting. –  Georges Elencwajg Commented May 11, 2011 at 9:52
• 1 I have no opinion on Kempf. Perhaps I should have used less loaded phrasing. I just meant that what's appropriate / acceptable for distinguished academicians isn't necessarily the best option for a somewhat more humble thesis-writer. Okay, it was OTT to baldly say your example supports the opposite view. But depending how you look at things, it supports either or neither position. –  FumbleFingers Commented May 11, 2011 at 13:44

Many people in academia encourage the use of “we” instead of “I”, although many other people don’t — I can easily remember that Chomsky, at least in Aspects of the Theory of Syntax , do use the first-person singular. Personally, I prefer to use “I”, if I’m the only author. I believe that it sounds much better, not to mention, humbler.

If you have an adviser, then you should really ask him. If you’re writing for a journal, see if they have published articles in which the author use “I” instead of “we”.

• 1 I like @Ryan Reich's answer better, to be honest. But you make the important additional point that much academic output can and should be guided by what's expected in context . Ask your advisor, mentor, editor or whatever if you don't already know that context. Don't do the 'unexpected' without being aware you're doing it, and having some idea how it'll go down. That would hardly be a rigorous academic approach. –  FumbleFingers Commented May 10, 2011 at 22:33
• @FumbleFingers, thank you. For some reason, I find the use of “we” to be conservative. Although science is not a solo task,there is nothing bad in remembering the reader that this is only your interpretation and findings about the subject. This is less obvious when reading seminal books on any area — by saying “I”, the author reminds us that he is human, and not a king ruling. –  rberaldo Commented May 10, 2011 at 22:54
• I think it's a finely-balanced thing, and all your arguments carry weight. The bottom line for OP should be 'ask the man', but we can afford to have our own personal positions. I only wrote one thesis, decades ago, and I bet I never used "I" once. Since then I've been in programming, and I nearly always use "we" in comments (in code that I wrote alone), even though most of that code was never likely to even be read by anyone except me. YMMD –  FumbleFingers Commented May 10, 2011 at 23:19

Remember that in situations like this, it is common for the author to refer to himself as "this author," e.g., "This author proposes a novel solution to the problem of X."

• In general this author is used only for personal opinions. "This author believes that the statistical tools used in most previous articles on this topic are inadequate" , but not "this author collected samples ..." –  Peter Shor Commented Nov 1, 2018 at 11:45

How about using neither? What about using factual voice instead :

"A new method to study cell differentiation in nematodes is proposed.""A new method to study cell differentiation in nematodes will be proposed." or "Figure 4.2 shows that..."

"A new method to study cell differentiation in nematodes will be proposed."

Was Replaced with :

"A new method to study cell differentiation in nematodes is proposed."

in accordance with suggestions (details in comments below).

• 4 That is passive. Nothing wrong with it, but that's what it is. –  Cerberus - Reinstate Monica Commented May 10, 2011 at 12:09
• 1 Nix the "will be" with "has been". I recommend using positive and factual statements, and not futuristic promises. By the time someone reads this, the works has already been done, and has been reported on. –  John Alexiou Commented May 10, 2011 at 16:33
• 2 "Figure 4.2 shows that..." Good: definitely an improvement over the original. "A new method to study cell differentiation in nematodes will be proposed." Terrible: this kind of use of the passive voice to avoid writing we or I makes papers much harder to read. –  Peter Shor Commented May 10, 2011 at 18:19
• #Peter : Thanks , What about "A new method to study cell differentiation in nematodes is proposed."? –  jimjim Commented May 10, 2011 at 22:27
• 2 @ja72: Not will be , not has been , A new method to study ... is proposed. You're proposing it as you write; the fact that the reader reads it later is completely immaterial; if you say has been , you are saying that you (or somebody else) proposed it in a previous paper. –  Peter Shor Commented Nov 1, 2018 at 11:36

Writing a dissertation for either a final-year project or a PhD is a large task. Here are a few thoughts to help along the way.

Preparatory reading

Your dissertation should be written in English. If this is not your native language, it is important that you ask someone literate to proof read your dissertation. Your supervisor only has a limited amount of time, so it would be sensible to ask two or three literate friends to read your dissertation before giving it to your supervisor. That way, he or she will be able to concentrate on the technical content without being distracted by the style.

Incidentally, it is a good idea to make sure that one of your readers is not a specialist in your area of research. That way they can check that you have explained the technical concepts in an accessible way.

Chapter 27 of Day's book gives some useful advice on the use (and misuse) of English.

• Tense — You should normally use the present tense when referring to previously published work, and you should use the past tense when referring to your present results. The principal exception to this rule is when describing experiments undertaken by others in the past tense, even if the results that they established are described in the present tense. Results of calculations and statistical analyses should also be in the present tense. So "There are six basic emotions [Ekman, 1972]. I have written a computer program that distinguishes them in photographs of human faces."
• Voice — The active voice is usually more precise and less wordy than the passive voice. So "The system distinguished six emotions" rather than "It was found that the system could distinguish six emotions".
• Person — The general preference nowadays is to write in the first person, although there is still some debate.
• Number — When writing in the first person, use the singular or plural as appropriate. For a dissertation with one author, do not use the "editorial we" in place of "I". The use of "we" by a single author is outrageously pretentious.
• The Future Perfect Web site has some useful hints and tips on English usage.
• Formality — A dissertation is a formal document. Writing in the first person singular is preferred, but remember that you are writing a scientific document not a child's diary. Don't use informal abbreviations like "don't".
• Repetition — Say everything three times: introduce the ideas, explain them, and then give a summary. You can apply this to the whole dissertation with introductory and closing chapters, and to each chapter with introductory and closing sections. However, do not simply copy entire paragraphs. The three variants of the text serve different purposes and should be written differently.
• Sidenotes — Avoid remarks in parentheses and excessive use of footnotes. If something matters, say it in the main text. If it doesn't matter, leave it out.
• References — Citations in brackets are parenthetical remarks. Don't use them as nouns. So "Ekman [1972] identifies six basic emotions" rather than "Six basic emotions are identified in [Ekman, 1972]".
• Simple language — Convoluted sentences with multiple clauses—especially nested using stray punctuation—make it harder for the reader to follow the argument; avoid them. Short sentences are more effective at holding the reader's attention.
• Remember the difference between adjectives and adverbs. Likely is an adjective, probably is an adverb. Purists would also say that due to is an adjectival preposition and owing to is adverbial, but this distinction is now largely lost (although because of probably reads better anyway).
• Try not to use nouns as adjectives. Alas, this is a common problem in Computer Science publications. At the very least, limit the number of nouns that are strung together.
• Try not to split infinitives. It is perfectly good English, but a lot of people don't like it.

Word processing

Learn how to use your word processor effectively. This will probably be MS Word or LaTeX. In either case, make sure that you now how to include numbered figures, tables of contents, indexes, references and a bibliography efficiently. With MS Word, learn how to use styles consistently. With LaTeX, consider a WYSIWYG editor such as LyX.

Think about your house style for pages and for things like fragments of computer programs.

Scholarly Voice: First-Person Point of View

First-person point of view.

Since 2007, Walden academic leadership has endorsed the APA manual guidance on appropriate use of the first-person singular pronoun "I," allowing the use of this pronoun in all Walden academic writing except doctoral capstone abstracts, which should not contain first person pronouns.

In addition to the pointers below, APA 7, Section 4.16 provides information on the appropriate use of first person in scholarly writing.

Inappropriate Uses:   I feel that eating white bread causes cancer. The author feels that eating white bread causes cancer. I found several sources (Marks, 2011; Isaac, 2006; Stuart, in press) that showed a link between white bread consumption and cancer.   Appropriate Use:   I surveyed 2,900 adults who consumed white bread regularly. In this chapter, I present a literature review on research about how seasonal light changes affect depression.

Confusing Sentence:   The researcher found that the authors had been accurate in their study of helium, which the researcher had hypothesized from the beginning of their project.   Revision:   I found that Johnson et al. (2011) had been accurate in their study of helium, which I had hypothesized since I began my project.

Passive voice:   The surveys were distributed and the results were compiled after they were collected.   Revision:   I distributed the surveys, and then I collected and compiled the results.

Appropriate use of first person we and our :   Two other nurses and I worked together to create a qualitative survey to measure patient satisfaction. Upon completion, we presented the results to our supervisor.

Make assumptions about your readers by putting them in a group to which they may not belong by using first person plural pronouns. Inappropriate use of first person "we" and "our":

• We can stop obesity in our society by changing our lifestyles.
• We need to help our patients recover faster.

In the first sentence above, the readers would not necessarily know who "we" are, and using a phrase such as "our society " can immediately exclude readers from outside your social group. In the second sentence, the author assumes that the reader is a nurse or medical professional, which may not be the case, and the sentence expresses the opinion of the author.

To write with more precision and clarity, hallmarks of scholarly writing, revise these sentences without the use of "we" and "our."

• Moderate activity can reduce the risk of obesity (Hu et al., 2003).
• Staff members in the health care industry can help improve the recovery rate for patients (Matthews, 2013).

Can You Use First-Person Pronouns (I/we) in a Research Paper?

Research writers frequently wonder whether the first person can be used in academic and scientific writing. In truth, for generations, we’ve been discouraged from using “I” and “we” in academic writing simply due to old habits. That’s right—there’s no reason why you can’t use these words! In fact, the academic community used first-person pronouns until the 1920s, when the third person and passive-voice constructions (that is, “boring” writing) were adopted–prominently expressed, for example, in Strunk and White’s classic writing manual “Elements of Style” first published in 1918, that advised writers to place themselves “in the background” and not draw attention to themselves.

In recent decades, however, changing attitudes about the first person in academic writing has led to a paradigm shift, and we have, however, we’ve shifted back to producing active and engaging prose that incorporates the first person.

Can You Use “I” in a Research Paper?

However, “I” and “we” still have some generally accepted pronoun rules writers should follow. For example, the first person is more likely used in the abstract , Introduction section , Discussion section , and Conclusion section of an academic paper while the third person and passive constructions are found in the Methods section and Results section .

In this article, we discuss when you should avoid personal pronouns and when they may enhance your writing.

It’s Okay to Use First-Person Pronouns to:

• clarify meaning by eliminating passive voice constructions;
• establish authority and credibility (e.g., assert ethos, the Aristotelian rhetorical term referring to the personal character);
• express interest in a subject matter (typically found in rapid correspondence);
• establish personal connections with readers, particularly regarding anecdotal or hypothetical situations (common in philosophy, religion, and similar fields, particularly to explore how certain concepts might impact personal life. Additionally, artistic disciplines may also encourage personal perspectives more than other subjects);
• to emphasize or distinguish your perspective while discussing existing literature; and
• to create a conversational tone (rare in academic writing).

The First Person Should Be Avoided When:

• doing so would remove objectivity and give the impression that results or observations are unique to your perspective;
• you wish to maintain an objective tone that would suggest your study minimized biases as best as possible; and
• expressing your thoughts generally (phrases like “I think” are unnecessary because any statement that isn’t cited should be yours).

Usage Examples

The following examples compare the impact of using and avoiding first-person pronouns.

Example 1 (First Person Preferred):

To understand the effects of global warming on coastal regions,  changes in sea levels, storm surge occurrences and precipitation amounts  were examined .

[Note: When a long phrase acts as the subject of a passive-voice construction, the sentence becomes difficult to digest. Additionally, since the author(s) conducted the research, it would be clearer to specifically mention them when discussing the focus of a project.]

We examined  changes in sea levels, storm surge occurrences, and precipitation amounts to understand how global warming impacts coastal regions.

[Note: When describing the focus of a research project, authors often replace “we” with phrases such as “this study” or “this paper.” “We,” however, is acceptable in this context, including for scientific disciplines. In fact, papers published the vast majority of scientific journals these days use “we” to establish an active voice.   Be careful when using “this study” or “this paper” with verbs that clearly couldn’t have performed the action.   For example, “we attempt to demonstrate” works, but “the study attempts to demonstrate” does not; the study is not a person.]

Example 2 (First Person Discouraged):

From the various data points  we have received ,  we observed  that higher frequencies of runoffs from heavy rainfall have occurred in coastal regions where temperatures have increased by at least 0.9°C.

[Note: Introducing personal pronouns when discussing results raises questions regarding the reproducibility of a study. However, mathematics fields generally tolerate phrases such as “in X example, we see…”]

Coastal regions  with temperature increases averaging more than 0.9°C  experienced  higher frequencies of runoffs from heavy rainfall.

[Note: We removed the passive voice and maintained objectivity and assertiveness by specifically identifying the cause-and-effect elements as the actor and recipient of the main action verb. Additionally, in this version, the results appear independent of any person’s perspective.] 

Example 3 (First Person Preferred):

In contrast to the study by Jones et al. (2001), which suggests that milk consumption is safe for adults, the Miller study (2005) revealed the potential hazards of ingesting milk.  The authors confirm  this latter finding.

[Note: “Authors” in the last sentence above is unclear. Does the term refer to Jones et al., Miller, or the authors of the current paper?]

In contrast to the study by Jones et al. (2001), which suggests that milk consumption is safe for adults, the Miller study (2005) revealed the potential hazards of ingesting milk.  We confirm  this latter finding.

[Note: By using “we,” this sentence clarifies the actor and emphasizes the significance of the recent findings reported in this paper. Indeed, “I” and “we” are acceptable in most scientific fields to compare an author’s works with other researchers’ publications. The APA encourages using personal pronouns for this context. The social sciences broaden this scope to allow discussion of personal perspectives, irrespective of comparisons to other literature.]

Other Tips about Using Personal Pronouns

• Avoid starting a sentence with personal pronouns. The beginning of a sentence is a noticeable position that draws readers’ attention. Thus, using personal pronouns as the first one or two words of a sentence will draw unnecessary attention to them (unless, of course, that was your intent).
• Be careful how you define “we.” It should only refer to the authors and never the audience unless your intention is to write a conversational piece rather than a scholarly document! After all, the readers were not involved in analyzing or formulating the conclusions presented in your paper (although, we note that the point of your paper is to persuade readers to reach the same conclusions you did). While this is not a hard-and-fast rule, if you do want to use “we” to refer to a larger class of people, clearly define the term “we” in the sentence. For example, “As researchers, we frequently question…”
• First-person writing is becoming more acceptable under Modern English usage standards; however, the second-person pronoun “you” is still generally unacceptable because it is too casual for academic writing.
• Take all of the above notes with a grain of salt. That is,  double-check your institution or target journal’s author guidelines .  Some organizations may prohibit the use of personal pronouns.
• As an extra tip, before submission, you should always read through the most recent issues of a journal to get a better sense of the editors’ preferred writing styles and conventions.

How To Write A Dissertation Or Thesis

8 straightforward steps to craft an a-grade dissertation.

By: Derek Jansen (MBA) Expert Reviewed By: Dr Eunice Rautenbach | June 2020

Writing a dissertation or thesis is not a simple task. It takes time, energy and a lot of will power to get you across the finish line. It’s not easy – but it doesn’t necessarily need to be a painful process. If you understand the big-picture process of how to write a dissertation or thesis, your research journey will be a lot smoother.  

In this post, I’m going to outline the big-picture process of how to write a high-quality dissertation or thesis, without losing your mind along the way. If you’re just starting your research, this post is perfect for you. Alternatively, if you’ve already submitted your proposal, this article which covers how to structure a dissertation might be more helpful.

How To Write A Dissertation: 8 Steps

• Clearly understand what a dissertation (or thesis) is
• Find a unique and valuable research topic
• Craft a convincing research proposal
• Write up a strong introduction chapter
• Review the existing literature and compile a literature review
• Design a rigorous research strategy and undertake your own research
• Present the findings of your research
• Draw a conclusion and discuss the implications

Step 1: Understand exactly what a dissertation is

This probably sounds like a no-brainer, but all too often, students come to us for help with their research and the underlying issue is that they don’t fully understand what a dissertation (or thesis) actually is.

So, what is a dissertation?

At its simplest, a dissertation or thesis is a formal piece of research , reflecting the standard research process . But what is the standard research process, you ask? The research process involves 4 key steps:

• Ask a very specific, well-articulated question (s) (your research topic)
• See what other researchers have said about it (if they’ve already answered it)
• If they haven’t answered it adequately, undertake your own data collection and analysis in a scientifically rigorous fashion
• Answer your original question(s), based on your analysis findings

In short, the research process is simply about asking and answering questions in a systematic fashion . This probably sounds pretty obvious, but people often think they’ve done “research”, when in fact what they have done is:

• Started with a vague, poorly articulated question
• Not taken the time to see what research has already been done regarding the question
• Collected data and opinions that support their gut and undertaken a flimsy analysis
• Drawn a shaky conclusion, based on that analysis

If you want to see the perfect example of this in action, look out for the next Facebook post where someone claims they’ve done “research”… All too often, people consider reading a few blog posts to constitute research. Its no surprise then that what they end up with is an opinion piece, not research. Okay, okay – I’ll climb off my soapbox now.

The key takeaway here is that a dissertation (or thesis) is a formal piece of research, reflecting the research process. It’s not an opinion piece , nor a place to push your agenda or try to convince someone of your position. Writing a good dissertation involves asking a question and taking a systematic, rigorous approach to answering it.

If you understand this and are comfortable leaving your opinions or preconceived ideas at the door, you’re already off to a good start!

Step 2: Find a unique, valuable research topic

As we saw, the first step of the research process is to ask a specific, well-articulated question. In other words, you need to find a research topic that asks a specific question or set of questions (these are called research questions ). Sounds easy enough, right? All you’ve got to do is identify a question or two and you’ve got a winning research topic. Well, not quite…

A good dissertation or thesis topic has a few important attributes. Specifically, a solid research topic should be:

Let’s take a closer look at these:

Attribute #1: Clear

Your research topic needs to be crystal clear about what you’re planning to research, what you want to know, and within what context. There shouldn’t be any ambiguity or vagueness about what you’ll research.

Here’s an example of a clearly articulated research topic:

An analysis of consumer-based factors influencing organisational trust in British low-cost online equity brokerage firms.

As you can see in the example, its crystal clear what will be analysed (factors impacting organisational trust), amongst who (consumers) and in what context (British low-cost equity brokerage firms, based online).

Need a helping hand?

Attribute #2:   Unique

Your research should be asking a question(s) that hasn’t been asked before, or that hasn’t been asked in a specific context (for example, in a specific country or industry).

For example, sticking organisational trust topic above, it’s quite likely that organisational trust factors in the UK have been investigated before, but the context (online low-cost equity brokerages) could make this research unique. Therefore, the context makes this research original.

One caveat when using context as the basis for originality – you need to have a good reason to suspect that your findings in this context might be different from the existing research – otherwise, there’s no reason to warrant researching it.

Attribute #3: Important

Simply asking a unique or original question is not enough – the question needs to create value. In other words, successfully answering your research questions should provide some value to the field of research or the industry. You can’t research something just to satisfy your curiosity. It needs to make some form of contribution either to research or industry.

For example, researching the factors influencing consumer trust would create value by enabling businesses to tailor their operations and marketing to leverage factors that promote trust. In other words, it would have a clear benefit to industry.

So, how do you go about finding a unique and valuable research topic? We explain that in detail in this video post – How To Find A Research Topic . Yeah, we’ve got you covered 😊

Step 3: Write a convincing research proposal

Once you’ve pinned down a high-quality research topic, the next step is to convince your university to let you research it. No matter how awesome you think your topic is, it still needs to get the rubber stamp before you can move forward with your research. The research proposal is the tool you’ll use for this job.

So, what’s in a research proposal?

The main “job” of a research proposal is to convince your university, advisor or committee that your research topic is worthy of approval. But convince them of what? Well, this varies from university to university, but generally, they want to see that:

• You have a clearly articulated, unique and important topic (this might sound familiar…)
• You’ve done some initial reading of the existing literature relevant to your topic (i.e. a literature review)
• You have a provisional plan in terms of how you will collect data and analyse it (i.e. a methodology)

At the proposal stage, it’s (generally) not expected that you’ve extensively reviewed the existing literature , but you will need to show that you’ve done enough reading to identify a clear gap for original (unique) research. Similarly, they generally don’t expect that you have a rock-solid research methodology mapped out, but you should have an idea of whether you’ll be undertaking qualitative or quantitative analysis , and how you’ll collect your data (we’ll discuss this in more detail later).

Long story short – don’t stress about having every detail of your research meticulously thought out at the proposal stage – this will develop as you progress through your research. However, you do need to show that you’ve “done your homework” and that your research is worthy of approval .

So, how do you go about crafting a high-quality, convincing proposal? We cover that in detail in this video post – How To Write A Top-Class Research Proposal . We’ve also got a video walkthrough of two proposal examples here .

Step 4: Craft a strong introduction chapter

Once your proposal’s been approved, its time to get writing your actual dissertation or thesis! The good news is that if you put the time into crafting a high-quality proposal, you’ve already got a head start on your first three chapters – introduction, literature review and methodology – as you can use your proposal as the basis for these.

Handy sidenote – our free dissertation & thesis template is a great way to speed up your dissertation writing journey.

What’s the introduction chapter all about?

The purpose of the introduction chapter is to set the scene for your research (dare I say, to introduce it…) so that the reader understands what you’ll be researching and why it’s important. In other words, it covers the same ground as the research proposal in that it justifies your research topic.

What goes into the introduction chapter?

This can vary slightly between universities and degrees, but generally, the introduction chapter will include the following:

• A brief background to the study, explaining the overall area of research
• A problem statement , explaining what the problem is with the current state of research (in other words, where the knowledge gap exists)
• Your research questions – in other words, the specific questions your study will seek to answer (based on the knowledge gap)
• The significance of your study – in other words, why it’s important and how its findings will be useful in the world

As you can see, this all about explaining the “what” and the “why” of your research (as opposed to the “how”). So, your introduction chapter is basically the salesman of your study, “selling” your research to the first-time reader and (hopefully) getting them interested to read more.

How do I write the introduction chapter, you ask? We cover that in detail in this post .

Step 5: Undertake an in-depth literature review

As I mentioned earlier, you’ll need to do some initial review of the literature in Steps 2 and 3 to find your research gap and craft a convincing research proposal – but that’s just scratching the surface. Once you reach the literature review stage of your dissertation or thesis, you need to dig a lot deeper into the existing research and write up a comprehensive literature review chapter.

What’s the literature review all about?

There are two main stages in the literature review process:

Literature Review Step 1: Reading up

The first stage is for you to deep dive into the existing literature (journal articles, textbook chapters, industry reports, etc) to gain an in-depth understanding of the current state of research regarding your topic. While you don’t need to read every single article, you do need to ensure that you cover all literature that is related to your core research questions, and create a comprehensive catalogue of that literature , which you’ll use in the next step.

Reading and digesting all the relevant literature is a time consuming and intellectually demanding process. Many students underestimate just how much work goes into this step, so make sure that you allocate a good amount of time for this when planning out your research. Thankfully, there are ways to fast track the process – be sure to check out this article covering how to read journal articles quickly .

Literature Review Step 2: Writing up

Once you’ve worked through the literature and digested it all, you’ll need to write up your literature review chapter. Many students make the mistake of thinking that the literature review chapter is simply a summary of what other researchers have said. While this is partly true, a literature review is much more than just a summary. To pull off a good literature review chapter, you’ll need to achieve at least 3 things:

• You need to synthesise the existing research , not just summarise it. In other words, you need to show how different pieces of theory fit together, what’s agreed on by researchers, what’s not.
• You need to highlight a research gap that your research is going to fill. In other words, you’ve got to outline the problem so that your research topic can provide a solution.
• You need to use the existing research to inform your methodology and approach to your own research design. For example, you might use questions or Likert scales from previous studies in your your own survey design .

As you can see, a good literature review is more than just a summary of the published research. It’s the foundation on which your own research is built, so it deserves a lot of love and attention. Take the time to craft a comprehensive literature review with a suitable structure .

But, how do I actually write the literature review chapter, you ask? We cover that in detail in this video post .

Step 6: Carry out your own research

Once you’ve completed your literature review and have a sound understanding of the existing research, its time to develop your own research (finally!). You’ll design this research specifically so that you can find the answers to your unique research question.

There are two steps here – designing your research strategy and executing on it:

1 – Design your research strategy

The first step is to design your research strategy and craft a methodology chapter . I won’t get into the technicalities of the methodology chapter here, but in simple terms, this chapter is about explaining the “how” of your research. If you recall, the introduction and literature review chapters discussed the “what” and the “why”, so it makes sense that the next point to cover is the “how” –that’s what the methodology chapter is all about.

In this section, you’ll need to make firm decisions about your research design. This includes things like:

• Your research philosophy (e.g. positivism or interpretivism )
• Your overall methodology (e.g. qualitative , quantitative or mixed methods)
• Your data collection strategy (e.g. interviews , focus groups, surveys)
• Your data analysis strategy (e.g. content analysis , correlation analysis, regression)

If these words have got your head spinning, don’t worry! We’ll explain these in plain language in other posts. It’s not essential that you understand the intricacies of research design (yet!). The key takeaway here is that you’ll need to make decisions about how you’ll design your own research, and you’ll need to describe (and justify) your decisions in your methodology chapter.

2 – Execute: Collect and analyse your data

Once you’ve worked out your research design, you’ll put it into action and start collecting your data. This might mean undertaking interviews, hosting an online survey or any other data collection method. Data collection can take quite a bit of time (especially if you host in-person interviews), so be sure to factor sufficient time into your project plan for this. Oftentimes, things don’t go 100% to plan (for example, you don’t get as many survey responses as you hoped for), so bake a little extra time into your budget here.

Once you’ve collected your data, you’ll need to do some data preparation before you can sink your teeth into the analysis. For example:

• If you carry out interviews or focus groups, you’ll need to transcribe your audio data to text (i.e. a Word document).
• If you collect quantitative survey data, you’ll need to clean up your data and get it into the right format for whichever analysis software you use (for example, SPSS, R or STATA).

Once you’ve completed your data prep, you’ll undertake your analysis, using the techniques that you described in your methodology. Depending on what you find in your analysis, you might also do some additional forms of analysis that you hadn’t planned for. For example, you might see something in the data that raises new questions or that requires clarification with further analysis.

The type(s) of analysis that you’ll use depend entirely on the nature of your research and your research questions. For example:

• If your research if exploratory in nature, you’ll often use qualitative analysis techniques .
• If your research is confirmatory in nature, you’ll often use quantitative analysis techniques
• If your research involves a mix of both, you might use a mixed methods approach

Again, if these words have got your head spinning, don’t worry! We’ll explain these concepts and techniques in other posts. The key takeaway is simply that there’s no “one size fits all” for research design and methodology – it all depends on your topic, your research questions and your data. So, don’t be surprised if your study colleagues take a completely different approach to yours.

Step 7: Present your findings

Once you’ve completed your analysis, it’s time to present your findings (finally!). In a dissertation or thesis, you’ll typically present your findings in two chapters – the results chapter and the discussion chapter .

What’s the difference between the results chapter and the discussion chapter?

While these two chapters are similar, the results chapter generally just presents the processed data neatly and clearly without interpretation, while the discussion chapter explains the story the data are telling  – in other words, it provides your interpretation of the results.

For example, if you were researching the factors that influence consumer trust, you might have used a quantitative approach to identify the relationship between potential factors (e.g. perceived integrity and competence of the organisation) and consumer trust. In this case:

• Your results chapter would just present the results of the statistical tests. For example, correlation results or differences between groups. In other words, the processed numbers.
• Your discussion chapter would explain what the numbers mean in relation to your research question(s). For example, Factor 1 has a weak relationship with consumer trust, while Factor 2 has a strong relationship.

Depending on the university and degree, these two chapters (results and discussion) are sometimes merged into one , so be sure to check with your institution what their preference is. Regardless of the chapter structure, this section is about presenting the findings of your research in a clear, easy to understand fashion.

Importantly, your discussion here needs to link back to your research questions (which you outlined in the introduction or literature review chapter). In other words, it needs to answer the key questions you asked (or at least attempt to answer them).

For example, if we look at the sample research topic:

In this case, the discussion section would clearly outline which factors seem to have a noteworthy influence on organisational trust. By doing so, they are answering the overarching question and fulfilling the purpose of the research .

For more information about the results chapter , check out this post for qualitative studies and this post for quantitative studies .

Step 8: The Final Step Draw a conclusion and discuss the implications

Last but not least, you’ll need to wrap up your research with the conclusion chapter . In this chapter, you’ll bring your research full circle by highlighting the key findings of your study and explaining what the implications of these findings are.

What exactly are key findings? The key findings are those findings which directly relate to your original research questions and overall research objectives (which you discussed in your introduction chapter). The implications, on the other hand, explain what your findings mean for industry, or for research in your area.

Sticking with the consumer trust topic example, the conclusion might look something like this:

Key findings

This study set out to identify which factors influence consumer-based trust in British low-cost online equity brokerage firms. The results suggest that the following factors have a large impact on consumer trust:

While the following factors have a very limited impact on consumer trust:

Notably, within the 25-30 age groups, Factors E had a noticeably larger impact, which may be explained by…

Implications

The findings having noteworthy implications for British low-cost online equity brokers. Specifically:

The large impact of Factors X and Y implies that brokers need to consider….

The limited impact of Factor E implies that brokers need to…

As you can see, the conclusion chapter is basically explaining the “what” (what your study found) and the “so what?” (what the findings mean for the industry or research). This brings the study full circle and closes off the document.

Let’s recap – how to write a dissertation or thesis

You’re still with me? Impressive! I know that this post was a long one, but hopefully you’ve learnt a thing or two about how to write a dissertation or thesis, and are now better equipped to start your own research.

To recap, the 8 steps to writing a quality dissertation (or thesis) are as follows:

• Understand what a dissertation (or thesis) is – a research project that follows the research process.
• Find a unique (original) and important research topic
• Craft a convincing dissertation or thesis research proposal
• Write a clear, compelling introduction chapter
• Undertake a thorough review of the existing research and write up a literature review
• Undertake your own research
• Present and interpret your findings

Once you’ve wrapped up the core chapters, all that’s typically left is the abstract , reference list and appendices. As always, be sure to check with your university if they have any additional requirements in terms of structure or content.  

Psst... there’s more!

Thank you, it was really helpful

unquestionably, this amazing simplified way of teaching. Really , I couldn’t find in the literature words that fully explicit my great thanks to you. However, I could only say thanks a-lot.

Great to hear that – thanks for the feedback. Good luck writing your dissertation/thesis.

This is the most comprehensive explanation of how to write a dissertation. Many thanks for sharing it free of charge.

Very rich presentation. Thank you

Thanks Derek Jansen|GRADCOACH, I find it very useful guide to arrange my activities and proceed to research!

Thank you so much for such a marvelous teaching .I am so convinced that am going to write a comprehensive and a distinct masters dissertation

It is an amazing comprehensive explanation

This was straightforward. Thank you!

I can say that your explanations are simple and enlightening – understanding what you have done here is easy for me. Could you write more about the different types of research methods specific to the three methodologies: quan, qual and MM. I look forward to interacting with this website more in the future.

Thanks for the feedback and suggestions 🙂

Hello, your write ups is quite educative. However, l have challenges in going about my research questions which is below; *Building the enablers of organisational growth through effective governance and purposeful leadership.*

Very educating.

Just listening to the name of the dissertation makes the student nervous. As writing a top-quality dissertation is a difficult task as it is a lengthy topic, requires a lot of research and understanding and is usually around 10,000 to 15000 words. Sometimes due to studies, unbalanced workload or lack of research and writing skill students look for dissertation submission from professional writers.

Thank you 💕😊 very much. I was confused but your comprehensive explanation has cleared my doubts of ever presenting a good thesis. Thank you.

thank you so much, that was so useful

Hi. Where is the excel spread sheet ark?

could you please help me look at your thesis paper to enable me to do the portion that has to do with the specification

my topic is “the impact of domestic revenue mobilization.

When you are about to begin, writing a thesis seems a long, difficult task. That is because it is a long, difficult task. Fortunately, it will seem less daunting once you have a couple of chapters done. Towards the end, you will even find yourself enjoying it – an enjoyment based on satisfaction in the achievement, pleasure in the improvement in your technical writing, and of course the approaching end. Like many tasks, thesis writing usually seems worst before you begin, so let us look at how you should make a start. First make up a thesis outline: several pages containing chapter headings, sub-headings, some figure titles (to indicate which results go where) and perhaps some other notes and comments. There is a section on chapter order and thesis structure at the end of this text. Once you have a list of chapters and, under each chapter heading, a reasonably complete list of things to be reported or explained, you have struck a great blow against writer's block. When you sit down to type, your aim is no longer a thesis – a daunting goal – but something simpler. Your new aim is just to write a paragraph or section about one of your subheadings. It helps to start with an easy one: this gets you into the habit of writing and gives you self-confidence. In an experimental thesis, the Materials and Methods chapter is often the easiest to write – just write down what you did; carefully, formally and in a logical order. How do you make an outline of a chapter? For most of them, you might try the method that I use for writing papers, and which I learned from my thesis adviser (Stjepan Marcelja): Assemble all the figures that you will use in it and put them in the order that you would use if you were going to explain to someone what they all meant. You might as well rehearse explaining it to someone else – after all you will probably give several talks based on your thesis work. Once you have found the most logical order, note down the key words of your explanation. These key words provide a skeleton for much of your chapter outline. Once you have an outline, discuss it with your adviser. This step is important: s/he will have useful suggestions, but it also serves notice that s/he can expect a steady flow of chapter drafts that will make high priority demands on his/her time. Once you and your adviser have agreed on a logical structure, s/he will need a copy of this outline for reference when reading the chapters which you will probably present out of order. If you have a co-adviser, discuss the outline with him/her as well, and present all chapters to both advisers for comments. It is encouraging and helpful to start a filing system. Open a word-processor file for each chapter You can put notes in these files, as well as text. While doing something for Chapter n, you will think "Oh I must refer back to/discuss this in Chapter m" and so you put a note to do so in the file for Chapter m. Or you may think of something interesting or relevant for that chapter. When you come to work on Chapter m, the more such notes you have accumulated, the easier it will be to write. (depending on the reliability of your computer and the age of your memory). Do not keep a back-up drive close to the computer in case the hypothetical thief who fancies your computer decides that s/he could use the drive as well. If you thesis file is not too large, a simple way of making a remote back-up is to send it as an email attachment to a consenting email correspondent; you could also send it to yourself. In either case, be careful to dispose of superseded versions so that you don't waste disk space, especially if you have bitmap images or other large files. Or you could use a drop-box or other more sophisticated system. You should also have a physical filing system: a collection of folders with chapter numbers on them. This will make you feel good about getting started and also help clean up your desk. Your files will contain not just the plots of results and pages of calculations, but all sorts of old notes, references, calibration curves, suppliers' addresses, specifications, speculations, notes from colleagues etc., which will suddenly strike you as relevant to one chapter or other. Stick them in that folder. Then put all the folders in a box or a filing cabinet. As you write bits and pieces of text, place the hard copy, the figures etc in these folders as well. Touch them and feel their thickness from time to time – ah, the thesis is taking shape. If any of your data exist only on paper, copy them and keep the copy in a different location. Consider making a copy of your lab book. This has another purpose beyond security: usually the lab book stays in the lab, but you may want a copy for your own future use. Further, scientific ethics require you to keep lab books and original data for at least ten years, and a copy is more likely to be found if two copies exist. If you haven't already done so, you should archive your electronic data, in an appropriate format. Spreadsheet and word processor files are not suitable for long term storage. by Joseph Slater is a good guide. While you are getting organised, you should deal with any university paperwork. Examiners have to be nominated and they have to agree to serve. Various forms are required by your department and by the university administration. Make sure that the rate limiting step is your production of the thesis, and not some minor bureaucratic problem. One of the big FAQs for scientists: is there a word processor, ideally one compatible with MS Word, but which allows you to type mathematical symbols and equations conveniently? One solution is LaTeX, which is powerful, elegant, reliable, fast and from or . The standard equation editor for MS Word is point and click, so extremely slow and awkward. In many versions, Word's equation editor can be reached via hotkey Alt-equals, and takes pseudo latex typed input (eg X_1 converts to X subscript 1) upon the next space or operator. It uses some different formats - eg () rather than the {} of latex to group things and interprets divisions rather than having to use \frac. Here's a link: It has been useful to know these as it seems biologists and latex don't mix! I strongly recommend sitting down with the adviser and making up a timetable for writing it: a list of dates for when you will give the first and second drafts of each chapter to your adviser(s). This structures your time and provides intermediate targets. If you merely aim "to have the whole thing done by [some distant date]", you can deceive yourself and procrastinate more easily. If you have told your adviser that you will deliver a first draft of chapter 3 on Wednesday, it focuses your attention. You may want to make your timetable into a chart with items that you can check off as you have finished them. This is particularly useful towards the end of the thesis when you find there will be quite a few loose ends here and there. Whenever you sit down to write, it is very important to write So write something, even if it is just a set of notes or a few paragraphs of text that you would never show to anyone else. It would be nice if clear, precise prose leapt easily from the keyboard, but it usually does not. Most of us find it easier, however, to improve something that is already written than to produce text from nothing. So put down a draft (as rough as you like) for your own purposes, then clean it up for your adviser to read. Word-processors are wonderful in this regard: in the first draft you do not have to start at the beginning, you can leave gaps, you can put in little notes to yourself, and then you can clean it all up later. Your adviser will expect to read each chapter in draft form. S/he will then return it to you with suggestions and comments. Your adviser will want your thesis to be as good as possible, because his/her reputation as well as yours is affected. Scientific writing is a difficult art, and it takes a while to learn. As a consequence, there will be many ways in which your first draft can be improved. So take a positive attitude to all the scribbles with which your adviser decorates your text: each comment tells you a way in which you can make your thesis better. As you write your thesis, your scientific writing is almost certain to improve. Even for native speakers of English who write very well in other styles, one notices an enormous improvement in the first drafts from the first to the last chapter written. The process of writing the thesis is like a course in scientific writing, and in that sense each chapter is like an assignment in which you are taught, but not assessed. Remember, only the final draft is assessed: the more comments your adviser adds to first or second draft, the better. Before you submit a draft to your adviser, run a spell check so that s/he does not waste time on those. If you have any characteristic grammatical failings, check for them. Your thesis is a research report. The report concerns a problem or series of problems in your area of research and it should describe what was known about it previously, what you did towards solving it, what you think your results mean, and where or how further progress in the field can be made. Do not carry over your ideas from undergraduate assessment: a thesis is not an answer to an assignment question. One important difference is this: the reader of an assignment is usually the one who has set it. S/he already knows the answer (or one of the answers), not to mention the background, the literature, the assumptions and theories and the strengths and weaknesses of them. The readers of a thesis do not know what the "answer" is. If the thesis is for a PhD, the university requires that it make an original contribution to human knowledge: your research must discover something hitherto unknown. Obviously your examiners will read the thesis. They will be experts in the general field of your thesis but, on the exact topic of your thesis, you are the world expert. Keep this in mind: you should write to make the topic clear to a reader who has not spent most of the last three years thinking about it. Your thesis will also be used as a scientific report and consulted by future workers in your laboratory who will want to know, in detail, what you did. Theses are also consulted by people from other institutions, and the library at your university will store a copy as a file on a server. The advantage is that your thesis can be consulted much more easily by researchers around the world. (See e.g. for the digital availability of research theses.) Write with these possibilities in mind. It is often helpful to have someone other than your adviser(s) read some sections of the thesis, particularly the introduction and conclusion chapters. It may also be appropriate to ask other members of staff to read some sections of the thesis which they may find relevant or of interest, as they may be able to make valuable contributions. In either case, only give them revised versions, so that they do not waste time correcting your grammar, spelling, poor construction or presentation. The short answer is: rather more than for a scientific paper. Once your thesis has been assessed and your friends have read the first three pages, the only further readers are likely to be people who are seriously doing research in just that area. For example, a future research student might be pursuing the same research and be interested to find out exactly what you did. ("Why doesn't the widget that Bloggs built for her project work any more? Where's the circuit diagram? I'll look up her thesis." "Blow's subroutine doesn't converge in my parameter space! I'll have to look up his thesis." "How did that group in Sydney manage to get that technique to work? I'll look up a copy of the thesis they cited in their paper.") For important parts of apparatus, you should include workshop drawings, circuit diagrams and computer programs, usually as appendices. (By the way, the intelligible annotation of programs is about as frequent as porcine aviation, but it is far more desirable. You wrote that line of code for a reason: at the end of the line explain what the reason is.) You have probably read the theses of previous students in the lab where you are now working, so you probably know the advantages of a clearly explained, explicit thesis and/or the disadvantages of a vague one. If you use a result, observation or generalisation that is not your own, you must usually state where in the scientific literature that result is reported. The only exceptions are cases where every researcher in the field already knows it: dynamics equations need not be followed by a citation of Newton, circuit analysis does not need a reference to Kirchoff. The importance of this practice in science is that it allows the reader to verify your starting position. Physics in particular is said to be a vertical science: results are built upon results which in turn are built upon results etc. Good referencing allows us to check the foundations of your additions to the structure of knowledge in the discipline, or at least to trace them back to a level which we judge to be reliable. Good referencing also tells the reader which parts of the thesis are descriptions of previous knowledge and which parts are your additions to that knowledge. In a thesis, written for the general reader who has little familiarity with the literature of the field, this should be especially clear. It may seem tempting to leave out a reference in the hope that a reader will think that a nice idea or an nice bit of analysis is yours. I advise against this gamble. The reader will probably think: "What a nice idea – I wonder if it's original?". The reader can probably find out via the net or the library. If you are writing in the passive voice, you must be more careful about attribution than if you are writing in the active voice. "The sample was prepared by heating yttrium..." does not make it clear whether you did this or whether Acme Yttrium did it. "I prepared the sample..." is clear. The text must be clear. Good grammar and thoughtful writing will make the thesis easier to read. Scientific writing has to be a little formal – more formal than this text. Native English speakers should remember that scientific English is an international language. Slang and informal writing will be harder for a non-native speaker to understand. Short, simple phrases and words are often better than long ones. Some politicians use "at this point in time" instead of "now" precisely because it takes longer to convey the same meaning. They do not care about elegance or efficient communication. You should. On the other hand, there will be times when you need a complicated sentence because the idea is complicated. If your primary statement requires several qualifications, each of these may need a subordinate clause: "When [qualification], and where [proviso], and if [condition] then [statement]". Some lengthy technical words will also be necessary in many theses, particularly in fields like biochemistry. Do not sacrifice accuracy for the sake of brevity. "Black is white" is simple and catchy. An advertising copy writer would love it. "Objects of very different albedo may be illuminated differently so as to produce similar reflected spectra" is longer and uses less common words, but, compared to the former example, it has the advantage of being true. The longer example would be fine in a physics thesis because English speaking physicists will not have trouble with the words. (A physicist who did not know all of those words would probably be glad to remedy the lacuna either from the context or by consulting a dictionary.) Sometimes it is easier to present information and arguments as a series of numbered points, rather than as one or more long and awkward paragraphs. A list of points is usually easier to write. You should be careful not to use this presentation too much: your thesis must be a connected, convincing argument, not just a list of facts and observations. One important stylistic choice is between the active voice and passive voice. The active voice ("I measured the frequency...") is simpler, and it makes clear what you did and what was done by others. The passive voice ("The frequency was measured...") makes it easier to write ungrammatical or awkward sentences. If you use the passive voice, be especially wary of dangling participles. For example, the sentence "After considering all of these possible materials, plutonium was selected" implicitly attributes consciousness to plutonium. This choice is a question of taste: I prefer the active because it is clearer, more logical and makes attribution simple. The only arguments I have ever heard for avoiding the active voice in a thesis are (i) many theses are written in the passive voice, and (ii) some very polite people find the use of "I" immodest. Use the first person singular, not plural, when reporting work that you did yourself: the editorial 'we' may suggest that you had help beyond that listed in your acknowledgments, or it may suggest that you are trying to share any blame. On the other hand, retain plural verbs for "data": "data" is the plural of "datum", and lots of scientists like to preserve the distinction. Just say to yourself "one datum is ..", "these data are.." several times. An excellent and widely used reference for English grammar and style is by H.W. Fowler. There is no need for a thesis to be a masterpiece of desk-top publishing. Your time can be more productively spent improving the content than the appearance. In many cases, a reasonably neat diagram can be drawn by hand faster than with a graphics package, and you can scan it if you want an electronic version. Either is usually satisfactory. A one bit (i.e. black and white), moderate resolution scan of a hand-drawn sketch will be bigger than a line drawing generated on a graphics package, but not huge. While talking about the size of files, we should mention that photographs look pretty but take up a lot of memory. There's another important difference, too. The photographer thought about the camera angle and the focus etc. The person who drew the schematic diagram thought about what components ought to be depicted and the way in which the components of the system interacted with each other. So the numerically small information content of the line drawing may be much more useful information than that in a photograph. Another note about figures and photographs. In the digital version of your thesis, do not save ordinary photographs or other illustrations as bitmaps, because these take up a lot of memory and are therefore very slow to transfer. Nearly all graphics packages allow you to save in compressed format as .jpg (for photos) or .gif (for diagrams) files. Further, you can save space/speed things up by reducing the number of colours. In vector graphics (as used for drawings), compression is usually unnecessary. In general, students spend too much time on diagrams – time that could have been spent on examining the arguments, making the explanations clearer, thinking more about the significance and checking for errors in the algebra. The reason, of course, is that drawing is easier than thinking. I do not think that there is a strong correlation (either way) between length and quality. There is no need to leave big gaps to make the thesis thicker. Readers will not appreciate large amounts of vague or unnecessary text. A deadline is very useful in some ways. You must hand in the thesis, even if you think that you need one more draft of that chapter, or someone else's comments on this section, or some other refinement. If you do not have a deadline, or if you are thinking about postponing it, please take note of this: . There will inevitably be things in it that you could have done better. There will be inevitably be some typos. Indeed, by some law related to Murphy's, you will discover one when you first flip open the bound copy. No matter how much you reflect and how many times you proof read it, there will be some things that could be improved. There is no point hoping that the examiners will not notice: many examiners feel obliged to find some examples of improvements (if not outright errors) just to show how thoroughly they have read it. So set yourself a deadline and stick to it. Make it as good as you can in that time, and then hand it in! (In retrospect, there was an advantage in writing a thesis in the days before word processors, spelling checkers and typing programs. Students often paid a typist to produce the final draft and could only afford to do that once.) Talk to your adviser about this. As well as those for the examiners, the university libraries and yourself, you should make some distribution copies. These copies should be sent to other researchers who are working in your field so that: Whatever the University's policy on single or double-sided copies, the distribution copies could be double-sided paper, or digital, so that forests and postage accounts are not excessively depleted by the exercise. Your adviser could help you to make up a list of interested and/or potentially useful people for such a mailing list. Your adviser might also help by funding the copies and postage if they are not covered by your scholarship. A CD with your thesis will be cheaper than a paper copy. You don't have to burn them all yourself: companies make multiple copies for several dollars a copy. The following comment comes from Marilyn Ball of the Australian National University in Canberra: "When I finished writing my thesis, a postdoc wisely told me to give a copy to my parents. I would never have thought of doing that as I just couldn't imagine what they would do with it. I'm very glad to have taken that advice as my parents really appreciated receiving a copy and proudly displayed it for years. (My mother never finished high school and my father worked with trucks - he fixed 'em, built 'em, drove 'em, sold 'em and junked 'em. Nevertheless, they enjoyed having a copy of my thesis.)" In the ideal situation, you will be able to spend a large part – perhaps a majority – of your time writing your thesis. This may be bad for your physical and mental health. Keep going – you're nearly there! Most PhDs will admit that there were times when we thought about reasons for not finishing. But it would be crazy to give up at the writing stage, after years of work on the research, and it would be something to regret for a long time. Writing a thesis is tough work. One anonymous post doctoral researcher told me: "You should tell everyone that it's going to be unpleasant, that it will mess up their lives, that they will have to give up their friends and their social lives for a while. It's a tough period for almost every student." She's right: it is certainly hard work, it will probably be stressful and you will have to adapt your rhythm to it. It is also an important rite of passage and the satisfaction you will feel afterwards is wonderful. On behalf of scholars everywhere, I wish you good luck! The list of contents and chapter headings below is appropriate for some theses. In some cases, one or two of them may be irrelevant. Results and Discussion are usually combined in several chapters of a thesis. Think about the plan of chapters and decide what is best to report your work. Then make a list, in point form, of what will go in each chapter. Try to make this rather detailed, so that you end up with a list of points that corresponds to subsections or even to the paragraphs of your thesis. At this stage, think hard about the logic of the presentation: within chapters, it is often possible to present the ideas in different order, and not all arrangements will be equally easy to follow. If you make a plan of each chapter and section before you sit down to write, the result will probably be clearer and easier to read. It will also be easier to write. an introduction. It is a résumé of your thesis. The introduction should be interesting. If you bore the reader here, then you are unlikely to revive his/her interest in the materials and methods section. For the first paragraph or two, tradition permits prose that is less dry than the scientific norm. If want to wax lyrical about your topic, here is the place to do it. Try to make the reader want to read the heavy bundle that has arrived uninvited on his/her desk. Go to the library and read several thesis introductions. Did any make you want to read on? Which ones were boring? This section might go through several drafts to make it read well and logically, while keeping it short. For this section, I think that it is a good idea to ask someone who is not a specialist to read it and to comment. Is it an adequate introduction? Is it easy to follow? There is an argument for writing this section – or least making a major revision of it – towards the end of the thesis writing. Your introduction should tell where the thesis is going, and this may become clearer during the writing. How many papers? How relevant do they have to be before you include them? Well, that is a matter of judgement. On the order of a hundred is reasonable, but it will depend on the field. You are the world expert on the (narrow) topic of your thesis: you must demonstrate this. A political point: make sure that you do not omit relevant papers by researchers who are like to be your examiners, or by potential employers to whom you might be sending the thesis in the next year or two. Another disadvantage is that your journal articles may have some common material in the introduction and the "Materials and Methods" sections. The exact structure in the middle chapters will vary among theses. In some theses, it is necessary to establish some theory, to describe the experimental techniques, then to report what was done on several different problems or different stages of the problem, and then finally to present a model or a new theory based on the new work. For such a thesis, the chapter headings might be: Theory, Materials and Methods, {first problem}, {second problem}, {third problem}, {proposed theory/model} and then the conclusion chapter. For other theses, it might be appropriate to discuss different techniques in different chapters, rather than to have a single Materials and Methods chapter. Here follow some comments on the elements Materials and Methods, Theory, Results and discussion which may or may not correspond to thesis chapters. but you should not reproduce two pages of algebra that the reader could find in a standard text. Do not include theory that you are not going to relate to the work you have done. When writing this section, concentrate at least as much on the physical arguments as on the equations. What do the equations mean? What are the important cases? When you are reporting your own theoretical work, you must include rather more detail, but you should consider moving lengthy derivations to appendices. Think too about the order and style of presentation: the order in which you did the work may not be the clearest presentation. Suspense is not necessary in reporting science: you should tell the reader where you are going before you start. Take care plotting graphs. The origin and intercepts are often important so, unless the ranges of your data make it impractical, the zeros of one or both scales should usually appear on the graph. You should show error bars on the data, unless the errors are very small. For single measurements, the bars should be your best estimate of the experimental errors in each coordinate. For multiple measurements these should include the standard error in the data. The errors in different data are often different, so, where this is the case, regressions and fits should be weighted (i.e. they should minimize the sum of squares of the differences weighted inversely as the size of the errors.) (A common failing in many simple software packages that draw graphs and do regressions is that they do not treat errors adequately. UNSW student Mike Johnston has written a that plots data with error bars and performs weighted least square regressions. It is at http://www.phys.unsw.edu.au/3rdyearlab/graphing/graph.html). You can just 'paste' your data into the input and it generates a .ps file of the graph. In most cases, your results need discussion. What do they mean? How do they fit into the existing body of knowledge? Are they consistent with current theories? Do they give new insights? Do they suggest new theories or mechanisms? Try to distance yourself from your usual perspective and look at your work. Do not just ask yourself what it means in terms of the orthodoxy of your own research group, but also how other people in the field might see it. Does it have any implications that do not relate to the questions that you set out to answer? This chapter should usually be reasonably short – a few pages perhaps. As with the introduction, I think that it is a good idea to ask someone who is not a specialist to read this section and to comment. , it may be appropriate to cite web sites. (Be cautious, and don't overuse such citations. In particular, don't use a web citation where you could reasonably use a "hard" citation. Remember that your examiners are likely to be older and more conservative.) You should give the URL and also the date you downloaded it. If there is a date on the site itself (last updated on .....) you should included that, too. If you have found these documents useful, please feel free to pass the address or a hard copy to any other thesis writers or graduate student organisations. Please do not sell them, or use any of the contents without acknowledgement. This document will be updated occasionally. If you have suggestions for inclusions, amendments or other improvements, please send them. Do so after you have submitted the thesis – I thank Marilyn Ball, Gary Bryant, Bill Whiten and J. Douglas, whose suggestions have been incorporated in this version. Substantial contributions will be acknowledged in future versions. I also take this opportunity to thank my own thesis advisers, Stjepan Marcelja and Jacob Israelachvili, for their help and friendship, and to thank the graduate students to whom I have had the pleasure to be an adviser, a colleague and a friend. Opinions expressed in these notes are mine and do not necessarily reflect the policy of the University of New South Wales or of the School of Physics. Why and how did I write this document? The need for it was evident so, as one of my PhD students approached the end of his project, I made notes of everything that I said to him about thesis writing. These notes became the plan for the first draft of this document, which has been extended several times since then. I am surprised that it has hundreds of readers each day. However, this is an important message about the web. It takes time and thought to make a good resource but, if you do, it can benefit a lot of people. When this document was first posted, the web was relatively new and feedback showed that people were often surprised to find what they sought. Now there is a tendency to take the web for granted: one is almost disappointed not to find what one is seeking. However, the web is only as good as the collective effort of all of us. The readers of this document will be scholars, experts and educators: among the many contributions you will make to knowledge and your communities, there may be contributions that should be made freely available, all over the world. Keep this observation about the web in the back of your mind for when you are not writing a thesis.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

• A Guide to Writing a PhD Thesis

Written by Ben Taylor

A PhD thesis is a work of original research all students are requiured to submit in order to succesfully complete their PhD. The thesis details the research that you carried out during the course of your doctoral degree and highlights the outcomes and conclusions reached.

The PhD thesis is the most important part of a doctoral research degree: the culmination of three or four years of full-time work towards producing an original contribution to your academic field.

Your PhD dissertation can therefore seem like quite a daunting possibility, with a hefty word count, the pressure of writing something new and, of course, the prospect of defending it at a viva once you’ve finished.

This page will give you an introduction to what you need to know about the doctoral thesis, with advice on structure, feedback, submission and more.

Beginning your phd thesis.

The first stage of your PhD thesis will usually be the literature review . We’ve already written a detailed guide to what the PhD literature review involves , but here’s what you need to know about this stage of your PhD:

• The literature review is a chance for you to display your knowledge and understanding of what’s already been written about your research area – this could consist of papers, articles, books, data and more
• Rather than simply summarising what other scholars have said about your subject, you should aim to assess and analyse their arguments
• The literature review is usually the first task of your PhD – and typically forms the first part or chapter of your dissertation

After finishing your literature review, you’ll move onto the bulk of your doctoral thesis. Of course, you’ll eventually return to the lit review to make sure it’s up-to-date and contains any additional material you may have come across during the course of your research.

PhD thesis research

What sets your PhD thesis apart from previous university work you’ve done is the fact that it should represent an original contribution to academic knowledge . The form that this original contribution takes will largely depend on your discipline.

• Arts and Humanities dissertations usually involve investigating different texts, sources and theoretical frameworks
• Social Sciences are more likely to focus on qualitive or quantitative surveys and case studies
• STEM subjects involve designing, recording and analysing experiments, using their data to prove or disprove a set theory

Depending on the nature of your research, you may ‘write up’ your findings as you go, or leave it until the dedicated ‘writing-up’ period, usually in the third year of your PhD. Whatever your approach, it’s vital to keep detailed notes of your sources and methods – it’ll make your life a lot easier when it comes to using references in your dissertation further down the line.

PhD thesis vs dissertation

It’s common to use the terms ‘thesis’ and ‘dissertation’ interchangeably, but strictly speaking there is a difference in meaning between them:

• Your thesis is your argument. It’s the conclusions you’ve arrived at through surveying existing scholarship in your literature review and combining this with the results of your own original research.
• Your dissertation is the written statement of your thesis. This is where you lay out your findings in a way that systematically demonstrates and proves your conclusion.

Put simply, you submit a dissertation, but it’s the thesis it attempts to prove that will form the basis of your PhD.

What this also means is that the writing up of your dissertation generally follows the formulation of your doctoral thesis (it’s fairly difficult to write up a PhD before you know what you want to say!).

However, it’s normal for universities and academics to use either (or both) terms when describing PhD research – indeed, we use both ‘thesis’ and ‘dissertation’ across our website.

Can I use my Masters research in my PhD thesis?

If you’re studying an MPhil, it’s normal to ‘ upgrade ’ it into a PhD. Find mroe information on our guide.

PhD thesis structure

Having completed your initial literature review and conducted your original research, you’ll move onto the next phase of your doctoral dissertation, beginning to sketch out a plan that your thesis will follow.

The exact structure and make-up of your doctoral thesis will vary between fields, but this is the general template that many dissertations follow:

• Introduction – This sets out the key objectives of your project, why the work is significant and what its original contribution to knowledge is. At this point you may also summarise the remaining chapters, offering an abstract of the argument you will go on to develop.
• Literature review – The introduction will generally lead into a write-up of your literature review. Here you’ll outline the scholarly context for your project. You’ll acknowledge where existing research has shaped your PhD, but emphasise the unique nature of your work.
• Chapters – After you’ve finished introducing your research, you’ll begin the bulk of the dissertation. This will summarise your results and begin explaining the argument you have based on them. Some PhDs will also include specific chapters on methodology and / or a recreation of the data you have developed. Others will develop your argument over a series of stages, drawing on sources and results as relevant.
• Conclusion – The dissertation will end with a final chapter that pulls together the different elements of your argument and the evidence you have provided for it. You’ll restate the significance of your project (and its all-important original contribution to knowledge). You may also take the opportunity to acknowledge the potential for further work or opportunities to apply your findings outside academia.
• Bibliography and appendices – At the end of your thesis, you’ll need to include a full list of the books, articles and data you’ve referenced in a bibliography. You may also need to provide additional information in the form of an appendix.

How long is a PhD thesis?

The length of a PhD thesis varies from subject to subject, but all are far longer than those for undergraduate or Masters degrees. Your university will usually set an upper limit – typically between 70,000 and 100,000 words, with most dissertations coming in at around 80,000 words.

Generally speaking, STEM-based theses will be a little shorter than those in the Arts, Humanities and Social Sciences.

Different universities (and departments) will have different policies regarding what counts towards the PhD thesis word count, so make sure you’re aware what is expected of you. Check with your supervisor whether references, the bibliography or appendices are included in the word count for your dissertation.

How many chapters should a PhD thesis have?

There’s no hard and fast rule for the numbers of chapters in a PhD thesis, but most will have four or five chapters (in addition to the introduction and conclusion). This is the sort of thing you’ll discuss with your supervisor when planning out your research.

Writing up your PhD thesis

Once you’ve conducted your research and settled upon your thesis, there’s only one thing left to do: get it down on paper. Appropriately enough, this final part of a PhD is often referred to as the ‘ writing up period ’.

This is when you produce the final dissertation, which will be submitted as the basis for your viva voce exam. The nature of this task can vary from PhD to PhD.

In some cases you may already have a large amount of chapter drafts and other material. ‘Writing up’ therefore becomes a process of re-drafting and assembling this work into a final dissertation. This approach is common in Arts and Humanities subjects where PhD students tend to work through stages of a project, writing as they go.

Alternatively, you may have spent most of your PhD collecting and analysing data. If so, you’ll now ‘write up’ your findings and conclusions in order to produce your final dissertation. This approach is more common in STEM subjects, where experiment design and data collection are much more resource intensive.

Whatever process you adopt, you’ll now produce a persuasive and coherent statement of your argument, ready to submit for examination.

PhD thesis feedback

Your supervisor will usually give you feedback on each chapter draft, and then feedback on the overall completed dissertation draft before you submit it for examination. When the thesis is a work-in-progress, their comments will be a chance for them to make sure your research is going in the right direction and for you to ask their advice on anything you’re concerned about. This feedback will normally be given in the form of a supervisory meeting.

Although your PhD supervisor will be happy to give you advice on your work, you shouldn’t expect them to be an editor – it’s not their responsibility to correct grammatical or spelling mistakes, and you should make sure any drafts you submit to them are as error-free as possible. Similarly, they won’t be willing to edit your work down to fit a particular word count.

Finishing your PhD thesis

When you’ve finished the final draft of your doctoral thesis and it’s been approved by your supervisor, you’ll submit it for examination. This is when it’s sent to the examiners who will conduct your viva.

Submitting your thesis involves printing enough copies for your examiners and the university’s repository. Don’t leave this until the last minute – printing multiple copies of a 300-page document is a substantial undertaking and you should always allow enough time to account for any possible glitches or issues with the printing process.

Your viva will usually take place within three months of submitting your thesis. You can find out more in our dedicated guide to the PhD viva . After your viva, your examiners will give you a report that confirms whether or not you need to make any changes to your thesis, with several different potential outcomes:

• Pass – You’ve received your doctoral qualification!
• Minor corrections – These are usually fairly small edits, tweaks and improvements to your thesis, which you’ll be given three months to implement
• Major corrections – For these substantial changes, you may have to rewrite part of your dissertation or complete extra research, with a six-month deadline

Most PhD students will need to fix some corrections with their thesis (hopefully not major ones). It’s very rare for a dissertation to be failed.

Once you’ve made any necessary changes to your thesis, you’ll submit it one last time (usually electronically).

If you have plans to publish all or part of your work, you may want to request an embargo so that it won’t be visible to the public for a certain time. 12 months is a fairly standard time period for this, although you may want to ask for a longer embargo if you know that you want to turn your thesis into a book or monograph.

How to Write a Thesis or Dissertation Introduction

Published on September 7, 2022 by Tegan George and Shona McCombes. Revised on November 21, 2023.

The introduction is the first section of your thesis or dissertation , appearing right after the table of contents . Your introduction draws your reader in, setting the stage for your research with a clear focus, purpose, and direction on a relevant topic .

Your introduction should include:

• Your topic, in context: what does your reader need to know to understand your thesis dissertation?
• Your focus and scope: what specific aspect of the topic will you address?
• The relevance of your research: how does your work fit into existing studies on your topic?
• Your questions and objectives: what does your research aim to find out, and how?
• An overview of your structure: what does each section contribute to the overall aim?

Table of contents

How to start your introduction, topic and context, focus and scope, relevance and importance, questions and objectives, overview of the structure, thesis introduction example, introduction checklist, other interesting articles, frequently asked questions about introductions.

Although your introduction kicks off your dissertation, it doesn’t have to be the first thing you write — in fact, it’s often one of the very last parts to be completed (just before your abstract ).

It’s a good idea to write a rough draft of your introduction as you begin your research, to help guide you. If you wrote a research proposal , consider using this as a template, as it contains many of the same elements. However, be sure to revise your introduction throughout the writing process, making sure it matches the content of your ensuing sections.

Prevent plagiarism. Run a free check.

Begin by introducing your dissertation topic and giving any necessary background information. It’s important to contextualize your research and generate interest. Aim to show why your topic is timely or important. You may want to mention a relevant news item, academic debate, or practical problem.

After a brief introduction to your general area of interest, narrow your focus and define the scope of your research.

You can narrow this down in many ways, such as by:

• Geographical area
• Time period
• Demographics or communities
• Themes or aspects of the topic

It’s essential to share your motivation for doing this research, as well as how it relates to existing work on your topic. Further, you should also mention what new insights you expect it will contribute.

Start by giving a brief overview of the current state of research. You should definitely cite the most relevant literature, but remember that you will conduct a more in-depth survey of relevant sources in the literature review section, so there’s no need to go too in-depth in the introduction.

Depending on your field, the importance of your research might focus on its practical application (e.g., in policy or management) or on advancing scholarly understanding of the topic (e.g., by developing theories or adding new empirical data). In many cases, it will do both.

Ultimately, your introduction should explain how your thesis or dissertation:

• Helps solve a practical or theoretical problem
• Addresses a gap in the literature
• Builds on existing research
• Proposes a new understanding of your topic

Receive feedback on language, structure, and formatting

Professional editors proofread and edit your paper by focusing on:

• Academic style
• Vague sentences
• Style consistency

See an example

Perhaps the most important part of your introduction is your questions and objectives, as it sets up the expectations for the rest of your thesis or dissertation. How you formulate your research questions and research objectives will depend on your discipline, topic, and focus, but you should always clearly state the central aim of your research.

If your research aims to test hypotheses , you can formulate them here. Your introduction is also a good place for a conceptual framework that suggests relationships between variables .

• Conduct surveys to collect data on students’ levels of knowledge, understanding, and positive/negative perceptions of government policy.
• Determine whether attitudes to climate policy are associated with variables such as age, gender, region, and social class.
• Conduct interviews to gain qualitative insights into students’ perspectives and actions in relation to climate policy.

To help guide your reader, end your introduction with an outline  of the structure of the thesis or dissertation to follow. Share a brief summary of each chapter, clearly showing how each contributes to your central aims. However, be careful to keep this overview concise: 1-2 sentences should be enough.

I. Introduction

Human language consists of a set of vowels and consonants which are combined to form words. During the speech production process, thoughts are converted into spoken utterances to convey a message. The appropriate words and their meanings are selected in the mental lexicon (Dell & Burger, 1997). This pre-verbal message is then grammatically coded, during which a syntactic representation of the utterance is built.

Speech, language, and voice disorders affect the vocal cords, nerves, muscles, and brain structures, which result in a distorted language reception or speech production (Sataloff & Hawkshaw, 2014). The symptoms vary from adding superfluous words and taking pauses to hoarseness of the voice, depending on the type of disorder (Dodd, 2005). However, distortions of the speech may also occur as a result of a disease that seems unrelated to speech, such as multiple sclerosis or chronic obstructive pulmonary disease.

This study aims to determine which acoustic parameters are suitable for the automatic detection of exacerbations in patients suffering from chronic obstructive pulmonary disease (COPD) by investigating which aspects of speech differ between COPD patients and healthy speakers and which aspects differ between COPD patients in exacerbation and stable COPD patients.

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

Research objectives describe what you intend your research project to accomplish.

They summarize the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

Scope of research is determined at the beginning of your research process , prior to the data collection stage. Sometimes called “scope of study,” your scope delineates what will and will not be covered in your project. It helps you focus your work and your time, ensuring that you’ll be able to achieve your goals and outcomes.

Defining a scope can be very useful in any research project, from a research proposal to a thesis or dissertation . A scope is needed for all types of research: quantitative , qualitative , and mixed methods .

To define your scope of research, consider the following:

• Budget constraints or any specifics of grant funding
• Your proposed timeline and duration
• Specifics about your population of study, your proposed sample size , and the research methodology you’ll pursue
• Any inclusion and exclusion criteria
• Any anticipated control , extraneous , or confounding variables that could bias your research if not accounted for properly.

• How to Write an Abstract for a Dissertation or Thesis
• Doing a PhD

What is a Thesis or Dissertation Abstract?

The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.

Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.

What is the Purpose of an Abstract?

The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.

Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.

How Long Should an Abstract Be?

If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.

Woodrow Wilson, the 28th President of the United States of America, once famously said:

The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.

What Makes a Good PhD Thesis Abstract?

Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.

A good abstract is one that can clearly explain to the reader in 300 words:

• What your research field actually is,
• What the gap in knowledge was in your field,
• The overarching aim and objectives of your PhD in response to these gaps,
• What methods you employed to achieve these,
• You key results and findings,
• How your work has added to further knowledge in your field of study.

Another way to think of this structure is:

• Introduction,
• Aims and objectives,
• Discussion,
• Conclusion.

Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.

How Do You Write a Good PhD Thesis Abstract?

The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.

Keep It Concise

Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.

Make a Unique Point Each Sentence

Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.

Explain Your Research

Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.

Keep It Factual

Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.

Write, Edit and Then Rewrite

Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.

Thesis and Dissertation Abstract Examples

Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.

Example of A Bad Abstract

Let’s start with an example of a bad thesis abstract:

In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.

What Makes This a Bad Abstract

Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.

Working through our checklist of the 6 key points you want to convey to the reader:

• There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
• There’s no explanation about where the gap in the knowledge is that this project attempted to address.
• We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
• There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
• The author also doesn’t tell us a single result of his research, let alone the key findings !
• There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .

This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.

A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.

Example of A Good Abstract

Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:

Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.

The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.

This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.

What Makes This a Good Abstract

Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:

• The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
• The gap in knowledge was how these materials will behave structural when used in aircraft engines.
• The aim was specifically to investigate how the components can fracture.
• The methods used to investigate this were a combination of computational and lab based experimental modelling.
• The key findings were the increased risk of fracture of these components due to the way they are manufactured.
• The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.

The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.

The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.

* title mentioned where specified on the Wolfe webpage.

Emma Blackett (she/they), is a PhD candidate in Communication Studies whose work is informed by queer/feminist studies, psychoanalytic theory, film studies, and ecocriticism. Her dissertation, “Psychoanalysis for a Blue Humanities”, offers a critique of environmental subjectivity, taking as its premise the failure of public communications about ecological collapse to provoke action adequate to halting it.

Sadie Couture is a PhD candidate in the Department of Art History and Communication Studies at McGill University working at the intersection of media history, sound studies, and science and technology studies. During her tenure as a Wolfe Fellow, she will be working on my dissertation project, entitled “Long Time, First Time: A History of Call-In Radio in the United States and Canada 1945-1975” which focuses on the origins, development, and conventionalization of call-in radio and traces how technologies, policies, economies, and cultural desires impacted the format and pummeled it—imperfectly—into the shape it is today. Calling-in—using a telephone to connect to a radio station and subsequently be broadcast live—is simultaneously a technical process, a feedback system, satisfies the ‘public good’ criterion of many regulatory regimes, offers an additional way to shape an audience, and generates cheap, usable content.

Jay Ritchie, is a PhD candidate in the Department of English. His SSHRC CGS-funded doctoral research examines how poets created what Fluxus artist Dick Higgins called “intermedia” art, where two or more different artistic media are combined to create an artwork both between and beyond the artwork’s component media. Situating the turn towards intermedia in the context of the emergence of digital technology, his research examines the effects of digitality on poetic production, circulation, and reception from 1970 to 2020.

“Apart from providing vital, sustaining support for research and dissertation writing in the final year of my PhD, the Wolfe Fellowship allows me to attend conferences on digital media, the digital humanities, and science and technology more broadly,” says Jay. “The opportunity to share the research I have conducted while supported by the fellowship and to learn from other academics deepens my intellectual engagement with science and technology in the arts.”

Maryam Roosta , is a PhD candidate in the department of Anthropology at McGill University. Her doctoral dissertation is focused on the practice of temporary marriage among disadvantaged women in Iran. In Twelver Shi’a Islam, temporary marriage or mut’ah is a contract lasting anywhere from an hour to 99 years between a man and an unmarried woman. While mut’ah has traditionally been an urban phenomenon, the introduction of internet has reshaped the social arrangements between men and women who intend to contract mut’ah. Maryam’s research shows that to better understand the boundaries between mut’ah and transactional intimate relations is necessary to attend to the ways in which digital technologies such as the internet both enable and constrain women in contracting such relationships. In addition to Wolfe fellowship, her doctoral research is supported by the Fonds de Recherche du Québec - Société et Culture (FRQSC) and Wenner-Gren foundation.

Mehak Sawhney (she/her) is a PhD candidate and Vanier Canada Graduate Scholar in Communication Studies at McGill University. Her doctoral project titled Audible Waters: Sounding and Surveilling the Indian Ocean traces the production of oceanic territory through underwater sonic technologies in postcolonial India and the subcontinental Indian Ocean. Through a focus on hydrography, military security, conservation, and resource extraction, the project explores the politics of underwater monitoring technologies such as sonars as well as scientific disciplines such as underwater acoustics and bioacoustics. In so doing the project offers media theoretical reflections on the idea of the planetary, ongoing submarine colonialisms, and geopolitically situated ways to think about the relationship between sound, media and the environment.

“The Wolfe fellowship will support me in completing my dissertation as a final year PhD candidate at McGill,” says Mehak. “My dissertation titled Audible Waters: Sounding and Surveilling the Indian Ocean focuses on the production of oceanic territory through underwater sonic technologies in postcolonial India and the subcontinental Indian Ocean. It is based on ethnographic and archival research in India and the US. The fellowship will be very helpful in supporting my work and stay for the next academic session as an international student in Canada.”

Muhe Yang is a PhD candidate in the School of Information Studies at McGill University. Her doctoral research investigates how to design technologies to better support the interrelated needs of older adults living alone for physical activity. Older adults engage in physical activity for myriad purposes, including health benefits, associated sensory pleasures, and increased opportunities of socializing. Yet, older adults, especially those living alone, often encounter various barriers to maintaining their exercise routines, contributing to inactivity and falling short of recommended physical activity levels. Those barriers, including health problems, lack of motivation and social support, lack of exercise resources, not only span across individual, social, and environmental levels but also are often interrelated, as revealed in Muhe’s research findings to date.

Writing a thesis acknowledgement: should I address the person as "you" or use 3rd person?

I'm writing an acknowledgment for my thesis. I looked at several written acknowledgments and realized that the people who are acknowledged are addressed by "you" rather than "He/She". For example,

"I'm thankful to Dr. Marry. You have been the weekly contact ...."

But I personally prefer to address them in a 3rd person format saying "She has been the weekly contact".

I'm wondering if my preference is wrong and not common.

• writing-style
• acknowledgement

• I strongly suggest using 3rd person in this case, for the reasons nicely outlined below in the Daniel Wessel's answer (+1). –  Aleksandr Blekh Commented Feb 11, 2016 at 19:49

I'd go (and did go) with the 3rd person format, for a simple reason: It's not a letter to that one person, nor a (handwritten) dedication/signed copy of a thesis. Instead it is something that is printed and which is (hopefully) read by more than this one person.

So you talk to a broad audience about that person , hence 3rd person . Only if it were a handwritten, personal message in one particular copy, I would ever go with "you".

(Another exception could be a dedication. In contrast to the acknowledgements the dedication is more specific and -- usually -- to one person or specific group of people, like family. In this case 'you' might also make sense, because here you address them personally.)

In my thesis I made an acknowledgement infographics. The logic was simply that nobody wants to read a dry acknowledgement page, so the best way to thank them is to make people want to read the page. In fact my thesis was often taken out of the shelf in my PhD department solely to look at it.

EDIT: here it is .

• 4 What a great idea! –  Aru Ray Commented Feb 12, 2016 at 7:20
• it's a good idea however i cannot put weight on the factors that contributed and helped me with the thesis. –  Ehsan Commented Feb 13, 2016 at 19:00
• I assume that you refer to the fact that the values are set without mathematical calculations. I did give some thought to guestimate the values, but the contributions follow a power law and some of the people acknowledged did not do much (bar for being important). I did get jovially asked what the units were and what the boundary conditions were, but nobody doubted that I was bad at maths simply because I had unitless arbitrary values in my infographic acknowledgement page. –  Matteo Ferla Commented Feb 13, 2016 at 19:25

I will offer a contrary opinion: thesis acknowledgements are generally yours with which to do whatever you wish, within reason. If you prefer second person, this is the one piece of scientific writing where you can definitely get away with it. If you want to write it in a sonnet, that's OK too.

I advocate for a mixed approach. In my thesis acknowledgements, each individual was initially introduced in the third person, essentially for the reasons Daniel Wessel has mentioned above. The goal is for the Acknowledgements section to be read by more people than just the ones you are acknowledging.

However, for a proper subset of the acknowledged individuals, namely those I wanted to highlight, I included short personal messages in the second person. The goal was to highlight these individuals, break the monotony of just listing names, and inject something personal and heartfelt into the text.

Here is an example:

I am deeply indebted to Professor Dumbledore for his constant and genuine support of all his students. I would not be where I am today without him. Albus, I miss you every day.

The actual acknowledgements I wrote can be found on my website (within my thesis) if you're interested.

• 2 Great idea, essentially the best of both approaches. :-) –  Daniel Wessel Commented Feb 12, 2016 at 9:08

Over the last couple of months, I have "read" plenty of PhD theses, and almost all exclusively used a 3rd person format, e.g. you might say
