Distinguished Professor of Psychiatry and Director of the Schizophrenia Program at UC San Diego School of Medicine, David Braff, MD practices within UCSD Medical Center Hillcrest at 200 West Arbor Drive. Braff is also Director and Lead Scientist of the NIH-funded Consortium on the Genetics of Schizophrenia (COGS), a multi-site genetics study based out of the same UCSD Department of Psychiatry historically chaired by Dr. Igor Grant, MD. His clinical and research work centers on schizophrenia, prepulse inhibition, sensorimotor gating, and neurocognitive endophenotypes used to identify genetic risk markers within affected families. He is a diplomate of the American Board of Psychiatry and Neurology and a Fellow of the American Psychiatric Association, slotting into the UCSD adolescent and young-adult psychosis pipeline that connects with child psychiatry researchers including Dr. Tony T. Yang, MD. The most complex work handled here involves treatment-resistant schizophrenia patients enrolled in COGS protocols, where genomic, electrophysiological, and neurocognitive testing inform medication decisions for first-episode and chronic psychosis cases.
