James Cleaver, PhD

Professor Emeritus, UCSF

With over 50 years dedicated to research in the life sciences, Jim Cleaver has established himself as a first-rate authority in the fields of radiotherapeutics and dermatology. Dr. Cleaver earned his Ph.D. in radiotherapeutics from University of Cambridge in 1964, after which he worked as a researcher at Harvard Medical School and later at UCSF.

In 1968, Dr. Cleaver began his first of many professorships at UCSF in the Department of Radiobiology. Over the course of his career, Dr. Cleaver has published nearly 300 peer-reviewed articles, and is a member of the National Academy of Sciences. For the past 30 years, Dr. Cleaver has concentrated his research on genetic regulation of the mechanism of DNA damage and repair from radiations and chemical carcinogens. Cleaver’s findings have long since expanded beyond the realm of skin cancer, having strong influences on the modern concept of cancer.
