Biography

Dr. Özcan Özdamar is a professor of the University’s Department of Biomedical Engineering. He has secondary appointments in otolaryngology, pediatrics and neuroscience at the University of Miami Miller School of Medicine. He regularly serves as a consultant and board member for various medical diagnostic companies and health care institutions. He received his Bachelor of Science in electrical engineering in 1971 from the Middle East Technical University in Ankara, Turkey, and earned master’s and doctorate degrees in biomedical engineering from Northwestern University, Evanston, Ill., in 1973 and 1976, respectively. Özdamar joined the University’s biomedical engineering faculty in 1983 and become department chair in 1997. Prior to coming to Miami, he was director of the Electrophysiology Laboratory at Michael Reese Hospital and Medical Center in Chicago, with secondary appointments in the Department of Otolaryngology at the University of Chicago. During his tenure as chair, the BME department has become one of the best-known medically oriented research and education centers in the United States. Özdamar’s research interests include sensory/neural dynamics; acquisition and processing of sensory/brain waves and auditory/visual evoked potentials; automated screening and testing; otoacoustic emissions; neurophysiological computer instrumentation; and intraoperative and awareness/anesthesia monitoring. Özdamar has published more than 100 articles in national and international medical and engineering journals, books and proceedings. Early in his career he was involved in the electrophysiology of the sensory-brain systems and worked on the single unit and compound action potentials and brain responses of auditory system in animals. Later he developed auditory and visual instrumentation and signal processing methods for human clinical and research applications. He has received several technology transfer awards from the National Institutes of Health for the development of sensory diagnostic systems. Some of the methods and instruments he helped develop are in use in clinical and research systems. These techniques include efficient, cost effective and innovative methods for vision and hearing testing/screening and neuromonitoring.
