Keith Black: In addition to just having the grades and the test scores, I had demonstrated an aptitude really for research and science early on. When I was with my father one summer at the University of Pennsylvania, I would hang around the research labs at the University of Pennsylvania, which led me ultimately to try to seek out a position in a research lab when I went back to Cleveland, which I actually had an opportunity to start in the tenth grade. So I was doing research at one of the hospitals — St. Luke’s Hospital in Cleveland — in tenth and eleventh grade, and essentially spent half of my twelfth grade year doing research in a surgical research lab, and published my first paper when I was 17 years old. So you know, I had demonstrated really a focus on science and research, which I think made me competitive for the program.
