Looking at different graduate programs to apply to for physics focusing on biological physics. Very different research going on from school to school in the field so most of the criteria I'm basing where I apply is what kind of research is listed. My understanding of the process at your given physics program is you find an adviser and then ask around to see who's research seems the most interesting to you and then the two of you develop a solid thesis project. So far I've been looking at school's with the idea that I could only do research with professors in the home department of physics. With biological physics being wildly interdisciplinary, the thought occurred of what if I did research with a professor in say bioengineering or biology/biochemistry. Is this typically allowed in PhD programs or would it vary from school to school? I've already seen that some schools such as SUNY Stony Brook or UCLA have institutes or centers for quantitative biological research. My guess is that places with these centers would allow the interdepartmental thesis work but that's just a guess.
