I've done some preliminary browsing, considering MSTP, and I've noticed most MD/PhD programs seem to put people in their various biomedical departments, like Immunology, etc. However, I've been considering a MD/PhD in medicinal chemistry, which is obviously not generally in the School of Medicine. One or two schools have explicitly mentioned the chem dept as a possible place, while others just hint that it's not limited to biomedical departments. Anybody know about how hard it is to do this sort of thing? Would you have to apply separately to the chem grad program since it's not in the School of Medicine?
