Overview
Robert L. Folmer earned B.A. and M.A. degrees in biology from San Francisco State University. He received his Ph.D. in Speech and Hearing Science from the University of California, San Francisco. At U.C.S.F., he conducted numerous EEG and evoked potential studies and evaluations for the Departments of Psychiatry, Neurology, Otolaryngology, and Neurosurgery. He also provided neurophysiological monitoring services during brain and spinal surgeries. In 1997, he joined the Department of Otolaryngology at Oregon Health & Science University where he maintains an appointment of Associate Professor. At OHSU, Dr. Folmer was part of the team that developed the Dangerous Decibels hearing loss prevention education program. He joined the NCRAR in 2007 and now serves as Program Manager for the VA National Sleep Medicine Program. His research projects/interests include transcranial magnetic stimulation (TMS) for relief of tinnitus; electrophysiological assessment of auditory processing; evaluation of auditory and cognitive functions in patients who have multiple sclerosis (MS), Parkinson Disease, or traumatic brain injury (TBI); epidemiology and effects of sleep apnea and insomnia in Veterans.
