write an abstract for a dissertation, project or thesis
What is an abstract, and why do I need one?
An abstract is a short (generally 100-200 words), stand-alone summary of your research. It provides a 'shop window' that readers can use to help them decide whether or not your research is worth reading - it's where you 'sell' your research, and for this reason the abstract is an important part of your dissertation. You'll need to include the following things in your abstract...
An introduction - what is the background to your topic and why is it important?
Aims and problem - what did you investigate and what problem were you trying to solve?
Methods - what research methods did you use?
Results - what did you discover?
Conclusions - what are the implications of your discoveries?
When do I write my abstract?
Although your abstract will appear at the start of your dissertation, abstract writing is one of the last tasks in the dissertation writing process. If you wait until the research is finished and the dissertation is written you'll have a clear idea what to include. It's also important not to include anything in your abstract that's not in your dissertation, so by writing the abstract last you'll know exactly what to include.
Top tip...
It's a good idea to read through your dissertation, making a note of keywords for each section. You can then use these keywords as the basis of your abstract.

How do I write an abstract?
The lists below cover some important do's and do nots of abstract writing:
Do...
make sure your abstract stands-alone. It should tell your readers everything they need to know about your dissertation
include keywords that will make your research easy to search for
stick to the word count
Do not...
don't waffle. Make every word count
use abbreviations you have not explained
include quotations or references (unless absolutely vital)
over-use technical language or jargon - your abstract should be inviting for your readers, not impenetrable.
Activity: writing your abstract - 30 minutes or possibly more
Your abstract should cover the main areas in your dissertation, and highlight novel methods, interesting results and important implications.
1. On a blank sheet of paper write the following headings:
Aims/problem
Motivation
Methods
Results
Conclusions
2. Under the first heading (Aims/problem) write a sentence about your research question or problem. What exactly were you investigating? It can be useful to give some background information about the topic too.
2. Next, under the heading Motivation, write about why your research was important, relevant or necessary. Why should your readers care?
3. Under the heading Methods, write about the research methods you used. Be sure to highlight any novel or interesting methods. Also note that if you are writing an abstract for a laboratory research project, you'll also need to write about any note-worthy materials you used.
4. Under the heading Results, write about what you discovered. Be specific and mention the significance of your results, if appropriate.
5. Finally, under the Conclusions heading, write about the implications of your results, paying special attention to why your research was important and interesting.
6. These notes are the basis of your abstract, you just need to link it all together within your word limit - easy!

How did you do?
This is an abstract taken from an undergraduate microbiology project report. This student needed to summarise a ten week research project in 300 words. We've divided the abstract into the headings used in the activity above, so you can see the sort of things you should be writing under each.
Don't worry if the content means nothing to you; it's the structure that is important.
Function of the cytoskeleton in the biology and pathogenicity of S. typhimurium
Aim/problem:
MreD is a bacterial actin homologue that is present in a number of rod-shaped bacteria. MreD appears to be essential for the maintenance of cell shape and its loss causes an extreme alteration in cell morphology from rod-shaped to spherical, often followed by cell lysis. This study examines the impact on morphology and virulence of an mreD gene deletion in Salmonella enterica
Motivation:
To date, the roles of the Mre proteins have only been studied in non-pathogenic bacteria. This study looks at the effect of deletion of the mreD gene in Salmonella enterica servovar Typhimurium, a Gram-negative rod-shaped bacterium that is a major cause of gastroenteritis.
Methods:
An insertional disruption of the mreD gene is constructed and a range of phenotypic assays are undertaken to examine the impact of the deletion on the pathogenicity of S. typhimurium.
Results:
It is found that the disruption mutant has a spherical morphology. There is also evidence of an impact on several virulence factors, including LPS structure, flagella expression, and oxidative stress resistance. Fluorescence microscopy is used to demonstrate that MreD localizes around the periphery of the cell.
Conclusions:
This study provides evidence to suggest a role for the cytoskeleton in the pathogenicity of Salmonella which could prove useful in the search for an attenuated vaccine strain or a novel antimicrobial agent.
