Massachusetts General Hospital, consistently ranked among america's best hospital. They offer an internship program to undergrads where you can do clinical research or bench research. When I was in it you really had no say of who you wanted to work with (some people may have been matched through their essays, but i don't know) but I was paired with an orthopedic surgeon. I shadowed him in clinic and in the OR. In return, I helped recruit patients for his study and also did some other types of small jobs for him. It was a good experience....apply! I was thinking someone from my "class" would be on here but maybe not!
