Dr. Ian Purcell strives towards the development of a world class Vestibular and Balance Institute. He currently practices clinical Neurology with an additional focus in OtoNeurology and Headache management. Dr. Purcell started by enrolling in the combined M.D./Ph.D. program in Neuroscience at the University of Texas Medical Branch, Galveston in September of 1989. In September 1991 he entered the Vestibular Neurophysiology Laboratory of Adrian A. Perachio, Ph.D. and received a total of six years of funding from the NASA Graduate Training Grant and The Texas Space Grant Consortium as a principal investigator. As a neurophysiologist, aviator, and Russian jet warbird enthusiast, he is very interested in providing insight as to how sensory information related to gravity is encoded and processed by the vestibular system to control oculomotor and postural reflexes as well as spatial orientation of the human body moving through a complex three-dimensional environment. Dr. Purcell is involved in the innovation of many new vestibular technologies and actively publishes research articles on the vestibular system. He continues to remain at the forefront of diagnosing and treating vestibular dysfunction.
