Research Interests

NORMAL HEARING AND AUDITORY BRAIN DEVELOPMENT: In my laboratory we use a wide range of research techniques to investigate the structure and function of the normal auditory system (asking the question: How do we normally hear?) Our studies focus both on the “mature” system, and on early developmental processes that form the auditory brain.

THE CAUSES AND CONSEQUENCES OF HEARING LOSS: We examine many different factors that can cause hearing loss, and determine what structural and functional changes occur to the inner ear and the central auditory brain.

MY RESEARCH MISSION: To increase our knowledge of the complex biological mechanisms that enable us to hear the world. With new insights, we work to prevent hearing loss and to promote normal auditory system development. For those with hearing loss, we strive to understand the exact nature of hearing deficits, and use this information towards achieving the best possible strategies for remediation and/or the planning of habilitation.
