Sumitrajit (Sumit) Dhar is Professor and Chair of Communication Sciences and Disorders at Northwestern University in Evanston, Illinois. Sumit trained at the University of Mumbai, India, Utah State University, and Purdue University in Audiology and Hearing Science. Sumit’s scientific interest is in cochlear mechanics and otoacoustic emissions as well as in delivery models of hearing healthcare. Work from Sumit’s lab has contributed to our understanding of the basic mechanisms of otoacoustic emission generation and propagation.

More recently, the focus of this work has shifted to developing clinical applications using otoacoustic emissions for the early and accurate detection of cochlear malfunction. In the area of hearing healthcare delivery, Sumit’s lab is working on developing tools to increase affordability and accessibility of hearing healthcare. Work in both these areas is funded by the National Institutes of Health. The Dhar laboratory has also received funding from various foundations and industry sponsors. 

Sumit has served as an associate editor of the American Journal of Audiology in the past and is the current Editor-In-Chief. Other than his editorial duties for the AJA, Sumit reviews scientific manuscripts for a wide range of journals in the field and scientific grant proposals for a variety of federal and private funding agencies.
