I am a senior physics BS student, applying to programs in condensed matter and high energy physics at the moment. However, I have always been interested in doing an MS in EE. Its sort of late this year though, and I can't apply for EE programs now. But that got me thinking: is it possible to start my PhD program in physics, and then switch to engineering while in grad school? What is the process for this? Do I re-apply? I know it sounds bad, but I don't know what to do with my life at the moment. I'm hoping that I might learn if physics grad school is for me, by doing a year of it. So I guess i'm just wondering the possibility and possible issues of swapping to EE MS (or PhD even) programs, after having completed a year of physics PhD program. Thanks!
