I liked everything in school. I enjoyed learning things, but I had no specific bent towards science until my grandfather, who died — that summer — of stomach cancer. And I had been trying to decide what I was going to study in college — I was just about to enter college — and decided that I really have finally an aim in life. I was going to do something about cancer. Well, that meant I had to take a science, and so it was either chemistry or biology, and I decided on chemistry. So it was really very clear in my mind from then on what I wanted to do. How I was going to get there I wasn’t so sure of.
