Lab Members


David Horn, M.D., M.S.

Primary Investigator

Dr. Horn is an Associate Professor in the Department of Otolaryngology-Head and Neck Surgery at the University of Washington and holds an adjunct appointment with the Department of Speech and Hearing
Sciences. He is a pediatric otolaryngologist and Co-director of the Pediatric Cochlear Implant Program at Seattle Children’s Hospital. His research employs behavioral (psychoacoustic) methods to study auditory development in pediatric cochlear implant patients. Dr. Horn’s research has been supported by the National Institutes of Health, American Otological Society, Seattle Children’s Research Fund, and private donations.

Dr. Horn earned his medical degree at the Medical College of Wisconsin and then completed an Otolaryngology residency at Indiana University. During residency, he completed 2 years of dedicated research with Drs. David Pisoni and Richard Miyamoto on cognitive and behavioral development in pediatric cochlear implant patients. His Pediatric Otolaryngology fellowship training was subsequently completed at the University of Pittsburgh and he joined the UW faculty in 2010. Originally from Los Angeles, Dr. Horn is thrilled to be back on the west coast. His lovely wife and three tempestuous daughters keep him busy enough when away from the hospital and the lab. When he has a free moment, he spends his time cycling, cooking, watching old movies, and playing guitar.
