I am deciding between Duke and UNC-Chapel Hill for a Chemistry Ph.D. I know UNC has a stronger chem program overall but I am looking to do more chem bio with biomed applications, and Duke has one of the best med schools. In terms of research groups, they're pretty balanced with 2-3 groups at each school that I could work for. So in re: pros/cons, UNC and Duke are tied for me. My question is: are students happier/less stressed at Duke or at UNC? I get that UNC has a top program and that likely comes with additional stress, but is it so bad I should choose Duke instead? I know that the programs at Columbia, Stanford, etc. are pretty cutthroat and stress-inducing and I am wondering if that is the case at UNC.
