Hi friends, I realize that my question is probably not particularly clear cut, but I would like to hear some opinions on it. I am wondering, is it better as an undergraduate to diversify your research experiences, or to specialize? Would it be better to try out a number of different fields for probably shorter amounts of time, or to stick with one group/field for a longer period of time? I realize that "better" is ill defined, but I did that on purpose. For instance, better for grad school admissions and better for personal development are both valid I think. I am asking because I've recently been offered a summer position in a lab very similar to the one I spent the last year in. Both rely heavily on hyperpolarization of gases and would fall under nuclear physics. I enjoy nuclear physics, but to be honest it's all I've experienced research wise. Would it be better for me to just build up significant experience in one field for grad school, and then do that sort of shopping once I've been accepted into a program? Or would it be best to show some variation now? For reference, I am finishing up my second year of undergrad. Thanks!
