Richard Ransohoff, M.D.

Entrepreneur-in-Residence

Richard is a physician-scientist who joined Third Rock Ventures in 2018 to focus on neuroinflammation research and development opportunities throughout the portfolio.

Richard is a distinguished academic and leader in the field of neuroinflammation. His research has focused on glial biology across the spectrum of neurological disease, with a particular emphasis on the functions of chemokines and chemokine receptors in the development and pathology of the central nervous system. He joins us most recently from Biogen (2014-2017) where he was vice president and senior research fellow of neuroimmunology. There, he led the neuroimmunology efforts to find targets for treatment of neurological disease and bring those relevant for acute neurology, pain and multiple sclerosis indications through clinical proof of concept. Before joining Biogen, Richard was at the Cleveland Clinic (1984-2014), where he founded and directed the Neuroinflammation Research Center in the Lerner Research Institute. He was also Professor of Molecular Medicine at the Cleveland Clinic Lerner College of Medicine at Case Western Reserve University and staff neurologist at the Mellen Center for Multiple Sclerosis Treatment and Research.

Richard has served on numerous editorial and scientific advisory boards (SAB), currently including SABs of the Gladstone Institute for Neurological Disease; the German Center for Research in Neurodegenerative Disease (DZNE); the Keystone Symposia and Chemocentryx. His extensive body of research encompasses more than 400 publications across the fields of neurology, neuroscience and neuroimmunology. As a physician, he was named annually (1996-2014) to the “Best Doctors in America” for his expertise in the clinical care of patients with multiple sclerosis. He also received the 2012 John Dystel Award from the National Multiple Sclerosis Society and American Academy of Neurology for multiple sclerosis research. Richard received his MD from Case Western Reserve University School of Medicine, where he was later a postdoctoral fellow in the Department of Molecular Biology and Microbiology.
 
Richard attended tiny Bard College with Donald Fagen and the late Walter Becker who founded Steely Dan; film-maker Christopher Guest; Chevy Chase and Blythe Danner. Still wonders why he’s not cool.
