Hari Bharadwaj

Active Mentor - currently hosting PULSe students for laboratory rotations and recruiting PULSe students into the laboratory; serves on preliminary exam committees

Current Research Interests:

The Systems Neuroscience of Auditory Perception lab (SNAPlab)​ is directed by Hari Bharadwaj, and is part of the Department of Speech, Language & Hearing Sciences, and the Weldon School of Biomedical Engineering. At SNAPlab, we study the biological computations and neural circuits that underlie auditory perception. In particular, we are interested in how we process sounds and analyze acoustic scenes in complex everyday environments. Complex scenes with multiple sound sources such as crowded restaurants and busy streets present unique challenges for both biological and machine audition.  SNAPlab integrates behavioral experiments, computational modeling, and an array of non-invasive physiological measurement and imaging tools to investigate these challenges in humans.
