David Hafler, William S. and Lois Stiles Edgerly Professor of Neurology and Professor Immunobiology, loves to kayak in the Long Island Sound, go for runs, and to pontificate on how we should train the next cadre of physician scientists. He decided early in his career (college) to make the understanding of multiple sclerosis as a life passion, and during this adventure became a clinical neurologist, immunologist, and geneticist. After spending 28 years at Harvard, he with great joy a number of years ago moved to Yale with his wife Janet (see her blurb), a Medical Educator. While he is the Breakstone Professor Emeritus at Harvard, he always sits on the Yale side at “The Game”. They have two wonderful children, Brian, an MD/PhD graduate and research ophthalmologist and Jason, a PhD in Genetics graduate involved in venture capital.
