I'm currently an undergraduate student in my junior year of college and am thinking about careers/graduate school. So far I have had research internships in solid state physics and astrophysics and I haven't liked either of them enough to pursue them as a career. I like experimental physics but I'm not too interested in the theory of solid state physics in particular. I always hear that solid state and medical physics are good fields to go into if you want a job in industry. Are others useful right now? I like nuclear physics, plasma physics, and optics but I don't want to be limited to academia. Are those fields used in industrial research? I did some research and there seems to be crossover with nuclear physics and nuclear medicine but I'm not sure how direct it is. Optics looks like it crosses over with a lot of other fields as well. I'm an American but I'd like to try to go to grad school or work in Europe after I graduate. I considered teaching high school in another country. Is it easy to do that do you need years of teaching experience in the U.S. first? I've taken circuits courses at school but I haven't liked them. I know I don't want to be an electrical engineer but I might like other branches of engineering. What are the jobs prospects for a nuclear engineer right now?
