The only one I've heard that does rolling is William and Mary as they do 1-2 waves of admission based on responses. (source: friends applied last year and I applied this year to WM. I haven't heard anything though. Last year my one friend didn't hear until almost april because of where they were on the waitlist other friend heard early one)
I haven't heard yet from Penn
I'm interested in the history of professionalization in science. My current research is more focused on Britain but I am hoping to look at more transnational trends in my PHD work. I'm particularly interested in the shift from 'learned' societies to actual scientific bodies. I applied to Penn, FSU, Michigan, Chicago, William and Mary, UB, UofR and Cornell.
