Hearing impairment resulting from sound exposure, environmental toxins, or genetic defects is a disabling condition that affects millions of people. I have worked to improve the understanding of common types of hearing impairment by investigating how the impairment affects neural information processing in the auditory system. In one approach, we are designing signal processing algorithms to restore normal neural representations of sounds in the auditory nerve. In a second, we are studying the secondary changes in neural processing which occur in the brain after damage to the auditory input. Both efforts have direct application to auditory prosthesis.
