Having studied general chemistry at undergraduate level, I wanted to branch out into a different area of research. Materials science seemed to have the balance of chemistry and engineering I was looking for. In the next five years, I would like to undertake several short term postdoctoral research projects of a chemistry/materials engineering nature. After that I would ideally like to continue similar research in the industrial sector, possibly in the USA or Europe.
If you are considering studying a PhD I would recommend you pick a PhD topic that you find interesting, one that will continue to inspire you for three to four years. If you manage that then a PhD can be enjoyable and rewarding, but it takes a lot of commitment.
