Bill is the William Rosenberg Professor of Medicine at the Dana-Farber Cancer Institute and Harvard Medical School and an Institute Member of the Broad Institute of MIT and Harvard. He is the Chief Scientific Officer and interim Chief Operating Officer at the Dana-Farber Cancer Institute. Bill’s lab focuses on how oncogenes cooperate to program cancer initiation and progression. He and his colleagues showed that dysregulation of both phosphatases and kinases plays a key role in cell transformation. His laboratory has pioneered the use of integrated functional genomic approaches to identify and validate cancer targets. The tools, models, and approaches that his laboratory has developed are widely used worldwide to discover and validate molecularly targeted cancer therapies. Bill has served as the President of the American Society for Clinical Investigation and has been elected to the Association of American Physicians. Dr. Hahn has been the recipient of many honors and awards including the Wilson S. Stone Award from M.D. Anderson Cancer Center (2000), a Howard Temin Award from the National Cancer Institute (2001), the Ho-Am Prize in Medicine (2010), the Richard and Hinda Rosenthal Award from AACR (2015), and the Claire and Richard Morse Award (2019).
