| Richard S. Chadwick, Ph.D., Senior Investigator |
 |
Dr. Chadwick received B.S. and M.S. degrees from Cornell University. He received his Ph.D. from Stanford University in 1971, where he studied light scattering phenomena in blood. Dr. Chadwick joined the engineering faculty at the Technion Israel Institute of Technology in 1971 where he began his studies on cochlear mechanics. He moved to UCLA as an assistant professor in 1975 where he continued this work with Julian Cole. Dr. Chadwick joined the Bioengineering and Instrumentation Branch at NIH in 1980, where he began research in cardiovascular dynamics, and then moved to the NIDCD as a Senior Investigator in 1996. He is an elected fellow of the American Institute of Medical and Biological Engineering. Dr. Chadwick�s laboratory is studying the biomechanics of cochlear fine-tuning.

Research Interests:
The aim of the Section on Auditory Mechanics is to improve basic understanding of the auditory periphery through the combined use of mathematical modeling of cochlear macro, micro, and nano mechanics together with structural, biophysical and physiological data.
We are studying the radial structure of the cochlear traveling wave by comparing radial modes computed from our fluid-solid interaction finite element code with video micrographs obtained from the hemicochlea preparation that are analyzed by our optical flow motion analysis code.
We are currently developing atomic force microscopy techniques for both imaging and measurement of mechanical properties of tissue isolated from the mammalian cochlea. These data will be incorporated into our modeling studies.
