Geoffrey T. Manley, MD, PhD is the Chief of Neurosurgery at Zuckerberg San Francisco General Hospital where he co-directs the UCSF Brain and Spinal Injury Center and is Professor and Vice Chairman of Neurosurgery at the University of California, San Francisco (UCSF). Dr. Manley is an internationally recognized expert in neurotrauma. In addition to a robust clinical practice at ZSFG, San Francisco and the Greater Bay Area’s level 1 trauma center, he leads national and international clinical research efforts in the study of the short- and long-term effects of traumatic brain injury (TBI). Building on the success of the seminal, national longitudinal study, TRACK-TBI, Geoff, as Contact Principal Investigator, along with a nationwide team of TBI experts, has recently launched the TRACK-TBI NETWORK, an innovative, precision-medicine driven consortium that will test Phase 2 drugs for TBI. The TRACK-TBI studies have created a modern precision medicine information commons for TBI that integrates clinical, imaging, proteomic, genomic, and outcome biomarkers to drive the development of a new TBI disease classification system, which could revolutionize diagnosis, direct patient-specific treatment, and improve outcomes. His over 275 published manuscripts reflect a wide range of research interests from molecular aspects of brain injury to the clinical care of TBI. He sits on the National Academies of Science, Engineering and Medicine’s Committee on VA Examinations for Traumatic Brain Injury and has served as a consultant for the Prehospital Guidelines Committee for the World Health Organization and on numerous clinical research committees for the National Institutes of Health, Centers for Disease Control, and Department of Defense.
