Hi all: I am halfway through my PhD in Philosophy. But of late, I've been wondering whether after doing PhD in a particular area of a discipline,can I switch my future post PhD research to some other areas of the same discipline, or would my expertise would always be considered from the perspective of my PhD topic area? Lets say if i am working on a topic in Ethics, and later on after PhD my interest shifts towards Philosophy of science or logic? Would love to know your thoughts on the issue. :)
