Our current research projects involve the scientific, engineering, and clinical aspects of cochlear and middle-ear biomechanics, hearing-loss prevention in high-noise environments, devices that deliver sound through the bone-conduction pathway, and the commercial development of a novel hearing aid that directly actuates the middle ear. These activities include physiological experiments for determining structure–function relationships within the hearing sensory system; imaging studies for obtaining the 3-D anatomy of the tiny structures within the middle ears and cochleae of multiple species; and the development of computational models that incorporate the imaging results, can be validated against the physiological results, and can be used to test hypotheses related to clinical and technological improvements for the treatment and prevention of hearing loss.
