How to Write Abstract Section for your Dissertation or Thesis ?

PhD Dissertation Abstract Section


An abstract is a concise summary that captures the essence of your PhD or Post Graduate dissertation. It provides readers with a snapshot of your research topic, methodology, findings, and implications. Think of it as a condensed version of your entire dissertation, where you distil the most important aspects of your work into a brief yet informative summary. The abstract serves as a quick reference for readers who want to grasp the key points of your research without delving into the full dissertation.

A well-written abstract holds significant importance for your thesis. It serves as a powerful tool to attract the attention of potential readers, such as academic colleagues, researchers, and professionals in your field. It is often the first impression they have of your research work. A well-crafted abstract can entice readers to delve deeper into your dissertation, while a poorly written abstract may fail to convey the significance and novelty of your research.

A compelling abstract not only captures the essence of your research but also showcases the value and impact of your findings. It allows readers to quickly assess whether your research aligns with their own interests and needs. Moreover, a well-constructed abstract can serve as a standalone piece that can be cited and referenced by others, increasing the visibility and reach of your work.
