  • 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.
