Research Topics

The aim of the section on Auditory Mechanics is to increase knowledge of the hearing process via an interweaving of mathematical, physical, and biological approaches and techniques. Advanced modeling techniques are used interactively with biophysical and structural data obtained from tissues in the organ of Corti to study cochlear physical phenomena related to the transduction of sound to auditory nerve impulses. Special emphasis is directed toward developing techniques to integrate subcellular, cellular, and macroscopic interactions.
