I didn't really know where to place this thread, so move it if it's in the wrong place. I'm a nuclear physicist graduating with my masters this academic year. I have a meeting scheduled with one of my professors of a medical physics course I have just finished. We will be discussing what topics he has available for a PhD. It might be useful to have some questions prepared which I really need to ask before considering the offer. Since I have no experience with a PhD I would like your input on this. All guidance is welcome!
