About William Shofner

Dr. Shofner co-directs the Auditory Physiology Lab with Dr. Robert Withnell. His broad research interests are in the area of comparative auditory science. He is particularly interested in understanding how the physical features of complex sounds are encoded or represented in the auditory nervous system and how these representations are then related to the perceptual attributes of the sound in humans and non-human mammals. Previous research focused on neurophysiology of auditory neurons in the brainstem and behavioral experiments based on operant-conditioning in chinchillas. Current research projects are focused on pitch, speech and timbre perception in human listeners. Dr. Shofner teaches courses in the areas of anatomy and physiology of the auditory system, central auditory neuroscience, and hearing science. He is a fellow in the Acoustical Society of America.
