I am preparing my file to the PHD committee of the program that I am interested on. I am working in a presentation letter to explain why I want to do a PHD. Any suggestions? I really do not have idea how to start it.
Thanks

Tell a story, why you took thi field, your early years and experiences(life exp not educational exp) Do'nt repeat what is on the CV but somthing extra that makes you stand out. I wrote for my chemistry phd how I spent my early years doing home experiments and how that encouraged me to look at chemistry as an option. Hope that helps
