Hello Physicsforums. The title states my main question, but there is a little bit more than is revealed there. 1. Can you become a nuclear physicist with a nuclear engineering PhD? 2. If not, then can I get a PhD in nuclear physics with a double major in mechanical engineering and mathematics, without a degree in physics? 3. What is the difference between a nuclear engineering PhD and a nuclear physics PhD? I ask these questions because I am very interested in nuclear science and I am especially interested in doing research in nuclear science. I'm a little bit confused about the job market in this field though. Most job outlook sources say that nuclear engineering is supposed to decline by 4% while nuclear physicist jobs are supposed to increase by ~8%. What they don't specifiy is whether or not this applies to nuclear engineering PhDs. I'm also curious because I want to know which doctorate will give me a better opportunity to continue to do research.
