How to Write a PhD Thesis? Steps, Structure, & Tips

A PhD thesis is the longest research paper written by a PhD student. It is a requirement for earning a doctorate degree. Students generally write the dissertation towards the end of their programme. Earning the degree depends on effort, hard work, and quality of work done. 

Writing a PhD thesis is based on a timeframe of approximately 1 to 3 or more years, so consistency is the key. Completing these scary research papers requires a lot of time, focus, and cognitive energy. That’s why students often get depressed and crushed when trying to meet the deadline and complete the assignment on time. 

This task will be less overwhelming if students possess excellent writing, research, critical thinking, and analysis skills. If not, this article will guide you through the steps. 

How to Write a PhD Thesis Step-By-Step?

Besides being the lengthiest and scariest part of a student's life, writing a dissertation can be rewarding in terms of learning opportunities and comprehension of the subject. When you are in your ABD (All but dissertation) status, these steps can assist you in writing a PhD thesis step by step. 

1. Understand the Requirements

The institute usually provides the specific requirements for writing a thesis, which changes institute-wise and discipline-wise. The requirements include details about the advised word count, formatting, and citation style (MLA, APA, Chicago). One standard requirement is that it must contribute to the field’s knowledge and familiarity with the subject. 

The word count of a PhD thesis usually ranges from 60,000 to 80,000, while the other specific requirements vary by discipline. 

2. Choose Your Topic Wisely

A topic that interests you can be the perfect topic as long as it fills a knowledge gap and is feasible well within the deadline. Because writing a thesis is a long and challenging task, if your topic doesn’t interest you, it becomes obvious to be more overwhelmed and depressed. 

Choose a topic that is researchable and relevant data is easily accessible. It should also not be very cluttered, as not everyone researches it. Your topic has to be unique and add value to the research field. 

3. Do Initial Research

After selecting an interesting topic for your PhD thesis, you need to do initial research to familiarise yourself with it, its scope, and relevant literature. This will give you the confidence of your selection and enable you to write a winning research proposal. 

In initial research, you must shortlist the literature you will review later in the rigorous research stage and finalise the research methodology. Once you have gathered enough information to get the proposal approved, you should move to the next stage. 

4. Develop a Detailed Proposal

Once you get familiar with the topic, it’s time to get the research approval from the committee. For that purpose, you need to write a detailed research proposal in which you discuss your research plan, thesis statement, and research questions. 

You will provide details such as the objectives, scope, and potential contributions of your research topic. This will demonstrate how your PhD thesis topic is worth researching. Secondly, you will provide details like the relevant literature you will review during the process and the research methodology you will utilise for data collection. 

The research proposal includes a somewhat resonating structure as of the thesis itself. Here is a standard research proposal format (it may change according to your research discipline). 

• Abstract (if the proposal is too long) 
• Title Page
• Introduction
• Literature Review
• Purpose of Study
• Research Design and Methodology
• Delimitations and Scope of Study
• Research Schedule
• Budget
• References

5. Conduct Rigorous Research

Once you choose your PhD thesis research topic, you should mentally prepare yourself for in-depth, thorough research. The main part of a thesis is the research part; that’s why it’s referred to as a research project. Before doing the rigorous research, you need to choose the research methodology and relevant literature to review. 

Literature Review

The literature review involves analysing the existing and relevant literature from credible sources. Students tend to detect major themes and ideas discussed in those sources and find the knowledge gaps.

Research Methodology

Choosing the research methodology according to the discipline and area of study is crucial for better or more precise results. Once you select the research design, i.e. survey, interview, or focus group, you need to conduct the practical research.

While conducting the rigorous research, make sure to take the necessary notes. Using the index and bibliography cards and noting the citations will ease the later process for you. Where you will be adding the references, of course, will help to avoid plagiarism (we’ll talk about plagiarism in detail in the next paragraphs)

6. Make an Outline Before Writing

Clarity of mind: that’s something that helps you achieve great things. You must make a detailed outline before you start writing your thesis practically, just as you crafted a detailed structure for your research proposal. The thesis layout would be different from that of the research proposal. 

A standard thesis structure includes the core chapters and supporting pages. Here is a standard outline for a PhD thesis. 

• Title page
• Abstract
• Introduction 
• Literature Review
• Methodology
• Findings
• Discussion
• Conclusion 
• References
• Appendices
• Acknowledgement page

Once you outline, you will know what you will discuss and under which chapter. With this clarity, the chances of getting stuck or into writer’s block are reduced dramatically. If you still feel stuck, getting help with the dissertation is worth it. 

7. Follow the University Guides

The PhD thesis research guidelines provided by the institute are the most ignored yet important guidelines. Most universities provide word count, styling, and citation guidelines. Suppose you work day and night on your dissertation to, in the end, listen to “Your thesis doesn’t align the requirements.” It's frustrating, right? And what if you do not have enough time to implement the proposed changes? You’ll be ruined. 

So, it’s necessary to read the guidelines two to three times, familiarise yourself with the requirements, and keep revisiting them frequently. 

8. Start Writing Early

Sometimes, we wait for the perfect circumstances to start, and those ideal moments never come. So, instead of waiting for the right time or resources, just start writing your PhD thesis as soon as possible. Thesis writing is a lengthy task, and completing it well within the deadline is important so you have time to refine it and make the changes proposed by the supervisor. 

Writing a dissertation is quite a lengthy task and has multiple hurdles, such as writer’s block, difficulties in finding relevant data, and problems in data collection methods. These factors have the probability of delaying your thesis submission. 

Stepping away from the PhD thesis is also crucial before you proofread and edit your work. You should start again with fresh eyes and a high potential for finding mistakes. Preparing for the thesis defence is another factor you should consider while writing your thesis. 

9. Seek Feedback Regularly

The feedback loop keeps you up to date. A feedback loop means you take the feedback, make the advised changes, and ask for input again. Repeating this process multiple times is called a feedback loop. Seeking the supervisor's review repeatedly will give you confidence in your PhD dissertation and the chance to improve it repeatedly.

Getting the review and making all the requested changes at once can become a headache. If you keep the feedback loop, the chances of getting flooded with mistakes to resolve become irrelevant. 

 10. Create Rough Drafts and Refine

If you start writing your thesis as a perfectionist from the first draft, you may get stuck in the process. Creating rough drafts and refining them later is a good writing strategy. Write down any thought that comes to your mind related to the subject. Refine the drafts carefully and try to find the irrelevant stuff you need to omit and coherence errors. 

You can refine the drafts using strategies like a feedback loop and make your PhD thesis less energy-draining. If you keep tweaking the thesis, your dissertation is less likely to be completed late. 

 11. Revise Thoroughly

Revising the thesis thoroughly is critical to ensure your work is up to the mark and requires no further improvements. Although you have to make the suggested improvements by the committee, make sure you don’t leave them there purposely. 

Once you submit the PhD thesis, you won’t be able to make changes before the committee checks it. Reread and revise the entire dissertation to ensure the argument makes sense and is clearly mentioned. Make sure your evidence is solid enough to defend your claims and is presented in correct coherence. 

Also, check that all the claims discussed in the research are evidence-backed and explained thoroughly. Your evidence or supporting material must be quoted from credible sources such as journals, previous research, books, or reliable articles. 

 12. Avoid Plagiarism

Intentional or unintentional plagiarism can spoil the credibility of the PhD thesis and your reputation as a researcher. You may also face penalties for being found guilty of this offence. You should paraphrase the sources while quoting them instead of stating them as they are. 

Students often use paraphrasing tools to do the work, but we recommend you do it yourself, as no tool can match the creativity of a human brain. Use the proper citations and utilise the required referencing style. 

 13. Rein in the References

Add the proper references following the institute's required citation style in the provided guidelines for your PhD thesis. The citation styles usually used are MLA, APA, Harvard, and Chicago. The allocation of referencing style is subject to the area of study and selected discipline. Different disciplines of study may require you to utilise references other than common ones, such as AMA, IEEE, Vancouver, and OSCOLA. 

State the references carefully, and try to avoid any sort of mistakes. Make sure to add all the references for the material you quoted or taken inspiration from. As stated before, utilise the bibliography or index cards to note the references in the research process to cater for the possibility of missing out on citations. 

 14. Proofread and Edit

You may need to read the rough draft multiple times in order to finalise it, such as proofreading it for coherence, grammar and punctuation, relevance, layout, and structural errors. In the end, rematch it with the guidelines provided by the institute and make sure it complements them well. 

Editing it thoroughly before you submit the PhD dissertation is crucial. Although you do get the chance to make the proposed changes and submit your thesis again, the detection of too many serious mistakes can end up getting your dissertation rejected. 

 15. Prepare for the Viva

Before preparing for the viva, step away from the PhD thesis and give yourself a short break to collect your thoughts and freshen your mind. The term “thesis defence” sometimes scares students, and the thought of defending their work in front of the committee makes them feel panicked. 

Although it is a stressful situation, only good preparation can help to deal with it. Read your thesis again and discuss the argument and ideas with some classmates or a parent to assess your understanding. Try to predict the potential questions and prepare answers for them. Utilise the study smart techniques to prepare the thesis viva, such as practising it in mock viva with your supervisor or classmates. Keep your preparations going and try to avoid the stress; make yourself ready for situations where you don’t know the answer. 

Tips to Write Each Thesis Section

As we discussed the fifteen steps to writing a winning PhD thesis, we can move on to tips for writing each section and what to cover in core chapters and other pages. 

1. Title Page

The first page of a thesis contains information regarding your course, institute and personal details. Here are the things you need to mention on the title page: 

• Title of thesis
• Student’s name
• Supervisor’s name
• Date of submission
• Department’s name
• Name of the institution 

Adding these details is compulsory because the title page is included in the structural pages of the dissertation. 

2. Abstract

An abstract is a brief summary of a PhD thesis. By reading the abstract of the PhD dissertation, readers can understand the objectives of writing the thesis. An abstract also answers the question of why the audience must read this. The maximum length of an abstract should not exceed  400 words. 

Some essential tips for writing  an abstract of a thesis are given below;

• Identify your purpose for writing a PhD thesis
• Explain the problem at hand.
• Explain your research methods. 
• Summarise the results of your thesis. 
• Give closure to your thesis.

3. Introduction 

The introduction is the first major chapter of a PhD dissertation. Most students write the introductory section before other chapters. No doubt, the introduction is the first major chapter of your PhD thesis, but it should be written after completing the rest of the chapters. It should be compelling and motivate the readers to read the rest of your thesis. 

Some essential tips for writing a persuasive introduction are given below;

• Explain the goals of writing the PhD thesis
• Provide sufficient background information so that readers can understand the significance of the research questions.
• Acknowledgement of the previous work. It is possible only if you have read many papers relevant to your thesis topic.

Try to explain the scope of your research methods.

4. Research Methodology

With the help of the PhD thesis research methodology chapter, you should convince the readers that your research is helpful for them and contribute something new to your subject area. To write a PhD dissertation, you must gather a huge amount of data either by adopting a qualitative or quantitative research methodology. The research methodology chapter will provide complete details about your data collection method. 

Some essential tips to describe your overall approach in the research methodology chapter are given below;

• Restate your research questions.
• Develop your overall research approach (either qualitative or quantitative). 
• Define your gathered data.
• Justify the audience why you didn’t use other research methods
• Cite all the sources that contribute to your choice of research methodology.
• Describe how to analyse the results

• Explain whether your findings are generalised or transferred.

5. Results

State all the findings and takeaways of your research in the results chapter. The results section of your PhD thesis will provide an idea to the readers whether you have achieved the required goals to write the PhD dissertation or not. You should summarise your research findings into clear and concrete statements of facts.

6. Discussion

You need to present certain things in the discussion section: personal interpretations, opinions based on the findings, effects of the results, and predictions for future results. 

Here are some best practices for the discussion chapter:

• Adopt a consistent tone
•  Restate your hypothesis
• Explain the findings of your literature
•  Defend the answers to your research questions
• Discuss all the unexpected findings of your research
•  Summary of the implications of your findings

7. Conclusions

The conclusion section summarises all major discussions of the thesis. While writing the conclusion chapter, avoid discussing any new ideas that haven't been explored throughout the section.   

• Summarise the strongest and most important statements of your thesis
• Summarise the new observations, interpretations and insights relevant to your topic idea
• You should also try to include the broader implications of the results of your thesis
• There is no need to repeat the abstract, introduction, and discussion sentences in the conclusion. Rather than you should summarise the main points in your words
