Jonathan Braun, MD, PhD

Professor and Chair, Pathology and Laboratory Medicine

Jonathan Braun, M.D., Ph.D., is a physician-researcher devoted to the roles of the immune system in resistance and susceptibility to inflammatory bowel disease and cancer. He is a professor and chair of Pathology and Lab Medicine at the David Geffen School of Medicine at UCLA. A native of Cleveland, Ohio, Dr. Braun was raised in Los Angeles, where he focused on violin performance. He was an undergraduate at Stanford University (BS, chemistry and biology), and did his MD and PhD studies at Harvard Medical School with Emil Unanue. After residency in Pathology at Brigham and Women’s Hospital, and a postdoctoral fellowship with David Baltimore at the Whitehead Institute, he joined the faculty at the UCLA School of Medicine in 1985. Through an integrated approach of molecular microbial ecology and metaproteomic and metabolite analysis, and human genetics, his research centers on the biology of mucosal interaction of host immunity with the local microbial community, and its impact on chronic mucosal inflammatory disease and cancer. He has published more than 140 primary research studies, 14 issued patents, and co-founded three biopharma companies. His recent national service includes Chair of the National Scientific Advisory Committee of the Crohn’s and Colitis Foundation, and President of the Federation of Clinical Immunology Societies. He still plays violin when possible.
