I'm working on writing my graduate school application right now. It was easy to talk about my academic qualifications and all the research I have done. But I don't know how specific I need to get when talking about what I'm interested in. I'm a chemistry major. I have a broad interest in fields spanning from materials to more biochem oriented. I am hoping to get to grad school and find a group to work with in order to make my decision. But I feel like I will hurt my chances if I indicate too strongly that I really am undecided about what field of chemistry to go into. Do I really need to say "this is the field I want to go into during graduate school" or is it ok to indicate that I have interests in multiple completely different fields?
