Christopher A. Shera

Christopher A. Shera is a Professor of Otolaryngology-Head and Neck Surgery at the University of Southern California. His research focuses on the physics of hearing, particularly the mechanics of the cochlea and the generation of otoacoustic emissions (OAEs). As co-head of the Auditory Physics Group, he investigates how the ear achieves extraordinary sensitivity and dynamic range through biological mechanisms rather than technological solutions.
