The introduction is the most important part of your PhD thesis as it will form the first impression of the work you have done. A thesis must have a clear and coherent introduction that provides the reader with overall background of the research. Since introduction is the first chapter of the dissertation or thesis, many students make a mistake by assuming that it must be written first. However, this is not true. It is much better to write introduction, abstract and conclusion after the rest of the dissertation has been completed. This is because in the introduction chapter you need to be familiar which gaps in literature your study fills, what methods you are using to make valid contributions to knowledge and whether or not your aims and objectives are attainable in practice.

There are some important tricks that can greatly improve PhD dissertation writing and are part of our PhD writing services. The tips provide good assistance to PhD students who want to effectively write his/her dissertation paper.


Generally, introduction needs to contain the following information:

  • Provide background information
  • Outline the main research gaps and how your study will contribute
  • Specific your research aim and objectives
  • Indicate the value of your research and provide a brief outline of the whole thesis

The background sub-section is usually the first one in the introduction chapter. This should provide just brief information about the study and the research problem. The rest of the sections can go in any order. Regarding the length of introduction, there is no rule on how long the dissertation introduction should be. However, it depends on the dissertation size and the introduction section is generally up to 10% of the overall word count of the thesis. It is also reasonable to include prominent authors and references in your introduction. You can include the most interesting and valuable findings in the literature to show the value of your research and how it links to the previous literature.


The background section serves the information function. That is, it demonstrates the topic and introduces the reader to the dissertation. It would be of significant support for the student to include background information to present the topic and the problem your research aims to solve. However, it is important to note that background should not be too large. The length of this sub-section depends on the paper size and length of the introduction. It is also important to write on the importance of the topic. It is not necessary to just write that it is interesting. The key of the dissertation is to demonstrate how the research fills the specific research gap. It is reasonable to begin your background with a few important aspects of your topic. It would be a good idea to write down a list of 5-7 readings that you consider the most influential for this research. It is also important to write just enough information in your background avoiding overloading the section with redundant information.


This section of your dissertation introduction provides information about your research focus, previous gaps in literature, contribution of your study and your research rationale. The key is to clarify the area(s) you want to research and explain why it is important and how your study contributes to the available knowledge and improves on what has already been researched. To improve quality of PhD dissertation writing it would be beneficial to link the research focus to the overall background and aims and objectives of your thesis. Hence, it is important to transition from the background section smoothly and coherently to your research focus.
