What are the differences between molecular/cell biology PhD programs offered by medical schools and those offered by general graduate schools (e.g. "arts and sciences"), in term of research area, funding, prestige, etc? For example, Columbia has a molecular biology PhD in their main campus as part of the graduate school and a separate biomedical sciences PhD program at their med campus. Would there be any reason to prefer one over the other (considering non-ecology work)? Cheers!
