    Professor of Otolaryngology - Head and Neck Surgery and, by courtesy, of Pediatrics and of Neurosurgery

    Current Research and Scholarly Interests Hearing loss can begin at any age and tends to progress. Ultimately, this may lead to deafness. Our research team seeks to understand the mechanisms of progressive hearing loss, to develop better techniques of diagnosing the cause of hearing loss in individual patients, and to optimize outcomes after cochlear implantation. We perform translational research using animal models of hearing loss and clinical research in both adult and pediatric patients to accomplish our goals.
