What is a thesis?
What is a dissertation, getting started, staying on track, thesis abstract, lit(erature) review.
A thesis is a long-term project that you work on over the course of a semester or a year. Theses have a very wide variety of styles and content, so we encourage you to look at prior examples and work closely with faculty to develop yours.
Before you begin, make sure that you are familiar with the dissertation genre—what it is for and what it looks like.
Generally speaking, a dissertation’s purpose is to prove that you have the expertise necessary to fulfill your doctoral-degree requirements by showing depth of knowledge and independent thinking.
The form of a dissertation may vary by discipline. Be sure to follow the specific guidelines of your department.
- PhD This site directs candidates to the GSAS website about dissertations , with links to checklists, planning, formatting, acknowledgments, submission, and publishing options. There is also a link to guidelines for the prospectus . Consult with your committee chair about specific requirements and standards for your dissertation.
- DDES This document covers planning, patent filing, submission guidelines, publishing options, formatting guidelines, sample pages, citation guidelines, and a list of common errors to avoid. There is also a link to guidelines for the prospectus .
- Scholarly Pursuits (GSAS) This searchable booklet from Harvard GSAS is a comprehensive guide to writing dissertations, dissertation-fellowship applications, academic journal articles, and academic job documents.
Finding an original topic can be a daunting and overwhelming task. These key concepts can help you focus and save time.
Finding a topic for your thesis or dissertation should start with a research question that excites or at least interests you. A rigorous, engaging, and original project will require continuous curiosity about your topic, about your own thoughts on the topic, and about what other scholars have said on your topic. Avoid getting boxed in by thinking you know what you want to say from the beginning; let your research and your writing evolve as you explore and fine-tune your focus through constant questioning and exploration.
Get a sense of the broader picture before you narrow your focus and attempt to frame an argument. Read, skim, and otherwise familiarize yourself with what other scholars have done in areas related to your proposed topic. Briefly explore topics tangentially related to yours to broaden your perspective and increase your chance of finding a unique angle to pursue.
Critical Reading
Critical reading is the opposite of passive reading. Instead of merely reading for information to absorb, critical reading also involves careful, sustained thinking about what you are reading. This process may include analyzing the author’s motives and assumptions, asking what might be left out of the discussion, considering what you agree with or disagree with in the author’s statements and why you agree or disagree, and exploring connections or contradictions between scholarly arguments. Here is a resource to help hone your critical-reading skills:

Conversation
Your thesis or dissertation will incorporate some ideas from other scholars whose work you researched. By reading critically and following your curiosity, you will develop your own ideas and claims, and these contributions are the core of your project. You will also acknowledge the work of scholars who came before you, and you must accurately and fairly attribute this work and define your place within the larger discussion. Make sure that you know how to quote, summarize, paraphrase , integrate , and cite sources to avoid plagiarism and to show the depth and breadth of your knowledge.
A thesis is a long-term, large project that involves both research and writing; it is easy to lose focus, motivation, and momentum. Here are suggestions for achieving the result you want in the time you have.
The dissertation is probably the largest project you have undertaken, and a lot of the work is self-directed. The project can feel daunting or even overwhelming unless you break it down into manageable pieces and create a timeline for completing each smaller task. Be realistic but also challenge yourself, and be forgiving of yourself if you miss a self-imposed deadline here and there.
Your program will also have specific deadlines for different requirements, including establishing a committee, submitting a prospectus, completing the dissertation, defending the dissertation, and submitting your work. Consult your department’s website for these dates and incorporate them into the timeline for your work.
Accountability
Sometimes self-imposed deadlines do not feel urgent unless there is accountability to someone beyond yourself. To increase your motivation to complete tasks on schedule, set dates with your committee chair to submit pre-determined pieces of a chapter. You can also arrange with a fellow doctoral student to check on each other’s progress. Research and writing can be lonely, so it is also nice to share that journey with someone and support each other through the process.
Common Pitfalls
The most common challenges for students writing a dissertation are writer’s block, information-overload, and the compulsion to keep researching forever.
There are many strategies for avoiding writer’s block, such as freewriting, outlining, taking a walk, starting in the middle, and creating an ideal work environment for your particular learning style. Pay attention to what helps you and try different things until you find what works.
Efficient researching techniques are essential to avoiding information-overload. Here are a couple of resources about strategies for finding sources and quickly obtaining essential information from them.

Finally, remember that there is always more to learn and your dissertation cannot incorporate everything. Follow your curiosity but also set limits on the scope of your work. It helps to create a folder entitled “future projects” for topics and sources that interest you but that do not fit neatly into the dissertation. Also remember that future scholars will build off of your work, so leave something for them to do.
An abstract is a short (approximately 200-word) summary or overview of your research project. It provides enough information for a reader to know what they will find within the larger document, such as your purpose, methodology, and results or conclusion. It may also include a list of keywords. An abstract is an original document, not an excerpt, and its contents and organization may vary by discipline.
A literature review establishes a set of themes and contexts drawn from foundational research and materials that relate to your project. It is an acknowledgment that your scholarship doesn’t exist in a vacuum. With the review, you identify patterns and trends in the literature to situate your contribution within the existing scholarly conversation.
What is a literature review? A literature review (or lit review, for short) is a critical analysis of published scholarly research (the "literature") related to a specific topic. Literature here means body of work, which traditionally was done in written form and may include journal articles, books, book chapters, dissertations and thesis, or conference proceedings. In the case of design, however, literature has an expanded breadth since the body of work is oftentimes not represented by words. A design review may include plans, sections, photographs, and any type of media that portrays the work.
A literature review may stand on its own or may be inside a larger work, usually in the introductory sections. It is thorough but not exhaustive--there will always be more information than you can reasonably locate and include. Be mindful of your scope and time constraints and select your reviewed materials with care. A literature review
- summarizes the themes and findings of works in an area
- compares and contrasts relevant aspects of literature on a topic
- critically assesses the strengths and omissions of the source material
- elaborates on the implications of their findings for one's own research topic
What does a literature review look like? Each discipline has its own style for writing a literature review; urban planning and design lit reviews may look different than those from architecture, and design lit reviews will look significantly different than reviews from the biological sciences or engineering. Look at published journal articles within your field and note how they present the information.
- Introduction: most scholarly articles and books will have a literature review within the introductory sections. Its precise location may vary, but it is most often in the first few paragraphs or pages.
Dedicated literature reviews: these are stand-alone resources unto themselves. You can search for "literature review" and a topic, and you may find that one already exists. These literature reviews are useful as models within your field, for finding additional sources to explore, and for beginning to map the general relationships within the scholarly conversation around your topic. Be mindful not to plagiarize the source material.
Database search tip : Add the phrase "literature review" to your search to find published literature reviews.
Browsing through theses and dissertations of the past can help to get a sense of your options and gain inspiration but be careful to use current guidelines and refer to your committee instead of relying on these examples for form or formatting.

While Sandel argues that pursuing perfection through genetic engineering would decrease our sense of humility, he claims that the sense of solidarity we would lose is also important.
This thesis summarizes several points in Sandel’s argument, but it does not make a claim about how we should understand his argument. A reader who read Sandel’s argument would not also need to read an essay based on this descriptive thesis.
Broad thesis (arguable, but difficult to support with evidence)
Michael Sandel’s arguments about genetic engineering do not take into consideration all the relevant issues.
This is an arguable claim because it would be possible to argue against it by saying that Michael Sandel’s arguments do take all of the relevant issues into consideration. But the claim is too broad. Because the thesis does not specify which “issues” it is focused on—or why it matters if they are considered—readers won’t know what the rest of the essay will argue, and the writer won’t know what to focus on. If there is a particular issue that Sandel does not address, then a more specific version of the thesis would include that issue—hand an explanation of why it is important.
Arguable thesis with analytical claim
While Sandel argues persuasively that our instinct to “remake” (54) ourselves into something ever more perfect is a problem, his belief that we can always draw a line between what is medically necessary and what makes us simply “better than well” (51) is less convincing.
This is an arguable analytical claim. To argue for this claim, the essay writer will need to show how evidence from the article itself points to this interpretation. It’s also a reasonable scope for a thesis because it can be supported with evidence available in the text and is neither too broad nor too narrow.
Arguable thesis with normative claim
Given Sandel’s argument against genetic enhancement, we should not allow parents to decide on using Human Growth Hormone for their children.
This thesis tells us what we should do about a particular issue discussed in Sandel’s article, but it does not tell us how we should understand Sandel’s argument.
Questions to ask about your thesis
- Is the thesis truly arguable? Does it speak to a genuine dilemma in the source, or would most readers automatically agree with it?
- Is the thesis too obvious? Again, would most or all readers agree with it without needing to see your argument?
- Is the thesis complex enough to require a whole essay's worth of argument?
- Is the thesis supportable with evidence from the text rather than with generalizations or outside research?
- Would anyone want to read a paper in which this thesis was developed? That is, can you explain what this paper is adding to our understanding of a problem, question, or topic?
