The first time I went to a thesis defense was the summer before my sophomore year, when I worked in a Chemistry lab . Alice (not her real name) defended her thesis after 6 six years in graduate school (average for department), and her defense went so well that no one realized how much hardship she had gone through just to define her thesis question. In fact, she did not know what direction she would follow until she was at the end of her fifth year. The collection of the data, however, took less than a year.
Why did it take her 5 years to define her thesis? It took a year and a half to pass her courses and exams (average), but she encountered many obstacles when she started working on her thesis. First, it was challenging to find a topic that was novel and realistic for her time-frame. Second, as a young graduate student she was not familiar with many of the laboratory techniques and she spent a lot of time troubleshooting equipment. Third, even when her experiments went well, the results were not exciting or publishable.
It seems that with so much uncertainty there is no use in writing a thesis proposal. Quite the contrary, a research proposal will give a framework you can work with as well as backup plans you can turn to when things do not go as planned. Many departments require (or at least suggest) a thesis proposal during your second or third year. Given the uncertain nature of research, how can you write a realistic thesis proposal? After interviewing over 100 PhD’s, I collected the four most important elements:
Choose a research area that you are passionate about. Regardless your field, you will have good days and bad days. On good days you will be enthusiastic and motivated to work. On bad days, you might question whether your research makes any sense, and you might even doubt your ability to graduate. If you pick a meaningful topic, the daily setbacks in your research will not bring you down. You will still be working in an important field, and you will be learning the skills and expertise necessary for your career.
Pick a topic that can be completed with the available resources in a reasonable amount of time.
Some students make the mistake of being too ambitious in their thesis plans. A good rule of thumb is to expect things to take three times longer than they would if everything went smoothly. Talk to your advisor about choosing a topic that is novel, realistic for your time frame, and can be completed given your resources (e.g. equipment, expertise and money).
Look for projects that incorporate marketable skills
Graduate school can seem (and feel) like eternity, but there is a light at the end of the tunnel. What will you do after you graduate? It is a good idea to look at job postings in your field to find out what employers are looking for, and then design a thesis that will prepare you for those types of jobs.
Have several backup plans in your thesis proposal in case you reach a dead end.
A former graduate student who finished his thesis in 4 years (when the average for his department was 5-6 years) attributed his success to a long list of backup plans. “I had at least three backup plans for every experiment. There were times when I had to resort to my third backup plan before things I got anything useful.”
Planning is crucial to success in graduate school, and the sooner you start visualizing the progression of your thesis and publications, the sooner you can get your thesis and career on track.
