I was born in Mexico City. I was born and raised in that city. I went to school — to college — in Mexico, eventually studying chemical engineering. But long before I went to college, I was already fascinated with science. I can remember playing with chemistry toys and microscopes and so on. So since I was a child, I really became very interested in science, and had as a goal to become a scientist and to pursue scientific research as a career. So eventually, when I finished college in Mexico, to become a researcher, I decided to go abroad. So first I spent a few years in Europe, and then eventually came to the United States, doing a Ph.D. at Berkeley in chemistry. That was the way in which I could actually achieve my goal of doing research for a living.
