Geoffrey T. Manley, MD, PhD

Professor in Residence
Co-Director and Principal Investigator, Brain and Spinal Injury Center
Chief of Neurotrauma, San Francisco General Hospital and Medical Center

The Neurosurgeon is a medical doctor with specialized training in treating patients with traumatic brain injuries. The Neurosurgeon may have to do brain surgery to help save a person's life. 

Current interests and activities

Dr. Manley's particular specialty interests lie in the repair of injury to the central nervous system. Among Dr. Manley's research interests are investigations of brain oxygenation during hemorrhagic shock, the role of aquaporin water channels in cerebral water transport, direct measurement of oxygenation and metabolic, cellular, and molecular responses in clinically relevant animal models of brain injury, and metabolic monitoring of severely injured patients during resuscitation and critical care.
