My research centers on bioelectrical science and biomedical engineering. As a typical project in bioelectrical science, I collaborate with medical school faculty in determining cell surface potential measurements that allow us to evaluate the condition of the cell in a variety of environments and stages of development.

The biomedical engineering area uses low-frequency sound to measure the performance of human and animal joints. We reduce reliance on x-ray and surgical procedures in joint evaluation. The human temporomandibular joint, the spine, limbs, general arthritic conditions, and dog hip dysplasia will form the basis of future work.

Another current investigation applies signal processing techniques to the improvement of speech intelligibility, both in normal and hearing-impaired subjects. Time and frequency domain methods are employed, with emphasis on the signal presented to the ear drum.

Some of my work is interdepartmental. For example, I work with a faculty member in mechanical engineering on a project to systemize the approach to aids for the handicapped.
