Hello, I've seen lots of friendly people giving good advice here and wanted share my current graduate school situation with you guys and see what your opinions/advice are. I recently graduated with a Physics B.S. and loved it. I have a strong interest in atomic physics and radiation interaction with matter in general. I have taken two graduate quantum mechanics courses this past year as well because I think it is fascinating. I applied for some graduate schools and got accepted into a Nuclear Engineering PhD program at Ohio State University and found a professor working on radiation detection and radiation sensors and am considering accepting the offer to work with him. In the back of my mind, I still think I would prefer to go for a PhD in Physics since I have always idolized physicists and I am more familiar with the subject matter/courses. If I go for the Nuclear Engineering PhD I would want to make it as physics related as possible, as in I would try to take all my electives as graduate physics courses and try to shoot for a research-oriented career whether in academia or a national lab, etc. My main concern is that, as of right now, I have very little interest in power plants and reactors, so I’m worried that going for a PhD in Nuclear Engineering will pigeonhole me into a field full of power plants and reactors when I really just want to conduct research in nuclear and radiation physics, whether it be experimental or simulation. The Nuclear Engineering PhD opportunity is right in front of me though, I could start now and I have professor to work with who has funding and everything; and if I chose a Physics PhD I’d have to reapply to all the schools next year and hope I get in and basically start this process over. My question is, could getting a PhD in Nuclear Engineering hold the potential for a fulfilling career in my area of interest? Or do you guys think that a PhD in Physics is what I should be going for and if I don’t, I will probably always regret not going for the Physics PhD. I know it’s a hard question to answer since nobody can predict the future but I’d be glad to hear anyone’s opinions on the matter or if anyone has any experience making such a big decision and how it panned out. Thank you.
