What Is a Dissertation?

A dissertation is a long-form piece of academic writing based on original research you conduct as the final step to completing a PhD program.  It requires solid research, writing, and analytical skills. You can confidently approach this significant project by understanding the dissertation process and structure. Let’s Look at the key elements of writing a high-quality dissertation.

Dissertation Committee and Prospectus Process

Once you’ve completed your coursework and other program requirements, you’ll advance to “ABD” status – All But Dissertation. This means you’ve finished everything except your actual dissertation.

Before starting writing, you must form your dissertation committee and prepare your prospectus or proposal. Your committee will typically consist of your advisor and a few other faculty members, potentially from interdisciplinary backgrounds. They will guide you through the dissertation process and ultimately decide whether you pass your defense and earn your PhD.

The dissertation proposal, or prospectus, is a crucial foundation for your research journey. This formal document, which you will typically present and defend before your dissertation committee, outlines the aims and objectives of your proposed study. It also demonstrates the relevance and importance of your chosen research topic. Once you have successfully defended your prospectus and received approval from your committee, you can conduct your in-depth research and begin the writing process for your full dissertation.

How to Write and Structure a Dissertation

The specific structure of your dissertation can vary based on several factors, including your academic field, the focus of your research, and your overall methodological approach. Dissertations in the humanities often take on a more essay-like structure, where you build a cohesive argument to support a central thesis, with chapters organized around different themes or case studies.

On the other hand, dissertations in the hard sciences and social sciences tend to follow a more standardized format. These typically include a review of the existing literature, a detailed methodology section, an analysis of your original research findings, and a presentation of your results—all structured across distinct chapters. Regardless of your discipline, the goal is to present your work clearly, logically, and well-organized in a way that effectively communicates your research process and contributions.
