I have two fields that I am interested in. Field A is historical and requires me to learn two new languages and I would love to focus on this first. Field B is more accessible, that is, there are no extra languages to learn or mathematical methods to comprehend. But it is a more contemporary discipline. I would like to move into this field afterwards.
How does one do this? The fields do not overlap much.
People are often saying 'the value of a PhD is to show that you can do research, so once you have shown this, there is no need for a second PhD. You can move into a new area on your own now.'
However, I feel like it is incredibly important who one's supervisor was, and I am not sure how seriously people would take me in Field B. I would be 'not really one of theirs', as it were. I am also not sure how to get a job in Field B, after having done a PhD in Field A. I could apply for jobs in Field A and try to somehow move into Field B. But then, if a university hires me, to do research & teach in Field A, which I studied for my PhD, how do I explain to them that I happen to have a paper ready in a completely different field? And how would I even find the time to write such a paper, considering that it will be expected of me to do research & publish in Field A - because, this is after all what they hired me for.
Questions, Questions, Questions. :)
