Hi, I would like to ask for your opinion. I am between 2 offers. One is a PhD at Durham and the other one is Cambridge's CASM. In Durham I can start right away with my research. It would take 3 years (at least in theory). And I got a fellowship which seems to be very prestigious and can be considered as an award (well, this is what they say, but honestly I don't know). However, I would still need to spend some time gathering knowledge in certain areas. On the other hand, Cambridge has 1 (or 2) lectures that really interest me, and could help me in future research. The reputation of the university and the department are worldwide known. However, there is no secured PhD place after the CASM (at least not in Cambridge), and overall (including the PhD) this would take more time than in Durham. I appreciate your comments.
