I'm being encouraged by the Phys Department of one of the schools I've applied to (my top choice) to also apply for a fellowship, specific to the school/department, that would increase my funding to 1.5x the standard RA for incoming students. This fellowship would lock me into a specific area of research for my first two years. While I am interested in this research, I'm not sure it's the most interesting research at the school or whether I'd want to do it long-term. Still, the money is pretty good and they're super-supportive of me applying for it. Thoughts?
