  I am a postdoctoral research associate working with Professor Carol Y. Espy Wilson in Speech communication lab and  Professor Shihab Shamma in Neural systems lab. My primary research interest  is in speech signal processing, particularly in speech production and auditory signal processing, i.e. how human produces speech and how speech is processed in human auditory system.
