Hari Bharadwaj is an Assistant Professor at Purdue University with a joint appointment in Speech, Language, and Hearing Sciences, and Biomedical Engineering. He received a B.Tech. in Electrical Engineering from Indian Institute of Technology, Madras, in 2006. He then received M.S. degrees in Electrical Engineering and Biomedical Engineering from the University of Michigan, Ann Arbor, in 2008. In 2014, he completed a Ph.D. in Biomedical Engineering at Boston University with a dissertation on how the representation of sound information by the auditory nerve and brainstem, even among those with clinically “normal” hearing, could influence one’s ability to listen in challenging hearing conditions. Hari’s post-doctoral work at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital used neuroimaging techniques to study the cortical processing of complex sounds in school-aged children, including those with autism spectrum disorders. For this work, he received the Emerging Research Grant from the Hearing Health Foundation in 2015. In 2016, he joined the faculty at Purdue, where his lab integrates behavioral experiments, computational modeling, and an array of non-invasive physiological measurement tools to investigate the neural mechanisms underlying auditory perception in humans. Hari is a member of the Association for Research in Otolaryngology and the Acoustical Society of America.
