Susan Desmond-Hellman has been chancellor of the University of California, San Francisco, for about two years now. She moved to the university after a successful career in the pharmaceutical industry, and is determined to make the school as famous in the eyes of the public as the Mayo Clinic for innovative biomedical research, The New York Times' Denise Grady says. Grady recently spoke with Desmond-Hellman, UCSF's first female chancellor.
