Ronald A. DePinho, M.D.


DePinho, internationally recognized for basic and translational research in cancer, aging and age-associated degenerative disorders, became
MD Anderson’s fourth full-time president on Sept. 1, 2011. In this role, he oversees all areas of MD Anderson. He joined the institution after 14 years at Dana-Farber Cancer Institute and Harvard Medical School in Boston, where he was founding director of the Belfer Institute for Applied Cancer Science. There, he guided major basic-translational research programs focused on brain, colorectal, pancreatic and prostate cancers.

His scientific program made fundamental discoveries underlying cancer in the aged and factors governing acquired and inherited degenerative disorders. He established the concept of tumor maintenance, discovered a core pathway of aging and demonstrated that aging is a reversible process. Also, he has constructed and used refined mouse models of cancer to identify many new cancer targets and diagnostics. Learn more.
