Geoffrey T. Manley, MD, PhD is the Chief of Neurosurgery at San Francisco General Hospital and Professor of Neurosurgery at the University of California San Francisco (UCSF). He is a trauma neurosurgeon with clinical interests in brain injury, spinal cord injury and neurocritical critical care. His translational research interests span from the laboratory to the bedside.

Dr. Manley is a graduate of the Medical Scientist Training Program at Cornell University Medical College, where he earned his medical degree as well as his doctorate degree in Neuroscience. He completed his residency in Neurosurgery at UCSF and a Postdoctoral Fellowship in Molecular Biophysics. Dr. Manley is also a faculty member of the California Institute for Quantitative Biosciences and the UCSF Center for Clinical and Translational Informatics.

Dr. Manley is an internationally recognized expert in neurotrauma. He has published over 120 manuscripts that reflect a wide range of research interests from molecular aspects of brain injury to the clinical care of head trauma patients. He has helped to define new molecular mechanisms of injury to the nervous system that may lead to new treatments for these devastating injuries. He is also considered a leader in the rapidly growing field of advanced neuromonitoring and clinical informatics for critical care. His many honors include the General Motors Trauma Research Award and the Trauma Research Award from the American College of Surgeons. He has served as a Consultant for the Prehospital Guidelines Committee for the World Health Organization and on a number of committees for the National Institutes of Health.
