Research Interests

Dr. Greene’s research focuses on the mechanics and physiology of the auditory system and hearing. His lab focuses on the effects of using hearing restoration devices, as well as the mechanisms of hearing loss during high level sound exposure. Studies on hearing restoration devices include investigating the causes of loss of residual acoustic hearing in cochlear implant patients, and transmission of sound via bone conduction. These devices often involve substantial surgical procedures that can cause injurious levels of inner ear stimulation. Likewise, normal use of these devices stimulate the inner ear with indirect, non-ossicular pathways, which can resulting in unexpected interactions and perceptions. Current studies are focusing on quantifying these effects, investigating their sources, and developing strategies to mitigate their negative effects.
