Today, Sumit is Associate Professor at the Roxelyn and Richard Pepper Department of Communication Sciences and Disorders at Northwestern University, where he teaches courses in audiology and applied hearing science and is actively involved in the operation of the AuD program. Research in his lab is primarily focused on the theory and practice of otoacoustic emissions as they relate to cochlear mechanics and auditory behavior. His research is currently funded by the National Institutes of Health and the Hugh Knowles Foundation at Northwestern University. He has also received funding from the Deafness Research Foundation in the recent past.++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++James W.
