Professor Harris directs NEIL lab with over 25 years of experience with rodent CNS injury models and in particular using MRI and PET to assess structure and function. He received his B.Sc. in Biology/Neuroscience from University of Portsmouth in 1988, and his Ph.D. in Physiology from King’s College London in 1991. Dr. Harris’s early focus of research addressed the question of optimal timing for intervention after the diagnosis of infantile hydrocephalus. Prior to joining University of California Los Angeles (UCLA), Dr. Harris received training in multimodality imaging techniques, including PET, structural MRI, fMRI, DTI, and Glucose/blood-flow autoradiography at Kings college University of London, University of Florida McKnight Brain Institute, the Royal College of Surgeons unit of Biophysics in the Institute of Child Health, and University of Cambridge Department of Neurosurgery. Subsequently, Dr. Harris conducted studies to address forebrain ischemic stroke looking at the potential use of non-invasive biomarkers to determine salvageable areas of brain. The studies were cited amongst primary reported findings on biophysical mechanism of the change in water diffusion after stroke. Dr. Harris currently resides as Professor in Residence of UCLA Department of Neurosurgery where he primarily conducts investigations on Traumatic Brain Injury and is the scientific director of UCLA 7T animal imaging core.
