Associate Professor; Fellow, Hugh Knowles Center
I study the physiology of the inner ear and middle ear. Current focus is on how sounds evoked by stimuli that are emitted by the ear (otoacoustic emissions) are generated within the living hearing organ and how these signals travel through the middle ear and into the ear canal where they can be detected by a sensitive microphone. Other interests include the middle ear muscle acoustic reflex, high frequency hearing and development and calibration of instrument to measure hearing function.

Jonathan Siegel

Jonathan Siegel is a neurobiologist with a long-standing interest in auditory physiology. He is an associate professor in the Roxelyn and Richard Pepper Department of Communication Sciences and Disorders, as well as an associate professor of neurobiology in the Weinberg College of Arts and Sciences. Siegel’s primary research interests are otoacoustic emissions and hair cell physiology. He is the principal investigator in the Otoacoustic Emissions Laboratory, and he is also a collaborator in the School of Communication’s Auditory Research Lab. Siegel has written and lectured widely on cochlear physiology and ultrastructure. He is a reviewer for a number of scientific journals, including Audiology and Neurotology, Journal of the Acoustical Society of America, and the Journal of Neuroscience. The courses he teaches include Advanced Neurobiology and Physiology, Neurobiology and Communication, and Otoacoustic Emissions: Theory and Practice.
