- Is doing two PhDs a good path? 18 answers
I'm an undergraduate student. I used to think that a PhD certifies a person as an expert in a specific topic of a specific field. I've now been told that while that's true, a PhD most importantly proves that you are capable of independent research in general.
A professor of fluid dynamics told me that if he wanted to shift his research to an unrelated topic like dog anatomy, rather than getting a second degree he would seek out successive projects that get progressively closer to his research interest (e.g. a project on modelling blood flow in a dog, etc.), until eventually he is working on his originally unrelated research interest.
Is the above approach generally valid? If it works, then what legitimate reason is there to get a second PhD?
