James O. Phillips, Ph.D.

Research Associate Professor. jop@u.washington.edu

Department of Otolaryngology-HNS

Dr. Phillips is a vestibular neurophysiologist with expertise in neural brainstem recording in awake behaving primates.  Dr. Phillips is also an expert on vestibular behavioral testing in human and non-human primates, and on development of vestibular function.  Dr. Phillips will direct the research program and be responsible for the coordination of the acute and chronic recording studies, as well as the development of multiunit recording in deep brainstem structures and implementation of the chronic stimulation device.  Dr. Phillips has administrative experience as director of two clinical services at the University of Washington and Children’s Hosptial, and as a PI and Co-Pi. Dr. Phillips will oversee and participate in both neural recording and behavioral experiments, analysis of data and publication of results from these studies.
