Hair cells are the sensory receptors of sound, motion, and spatial orientation. Exposure to excessively loud noise or certain drugs can permanently damage hair cells and their connections to nerve fibers. My lab investigates the cellular mechanisms of noise-induced and chemical hair-cell damage using zebrafish as a model for human hearing and deafness.

Research Interests: Speech perception by hearing-impaired listeners, especially cochlear implant users; perception of talker-specific properties of speech by cochlear implant users, perception of suprasegmental speech characteristics and its relation to learning words; psychoacoustic abilities of cochlear implant users and of persons with unilateral hearing loss.

Research in my lab focuses on the development and regeneration of sensory receptors and afferent neurons in the inner ear. 

My work focuses on understanding the role of the cerebellar nodulus and uvula (NU) in motion perception and spatial navigation. We aim to understand how NU processes the vestibular signals arriving directly or indirectly from the vestibular organs (otolith and semicircular canal afferents).
