Faculty & Staff Directory

Professor Bierer joined the UW Speech and Hearing Sciences Department in the fall of 2005.  She obtained her doctorate in Neuroscience at the University of Michigan (2001).  During a post-doctoral fellowship at the University of California at San Francisco, she obtained a Masters of Science degree in Audiology from San Francisco State University (2003).  Also during her time in the bay area, Professor Bierer, underwent clinical training at the Department of Otolaryngology at Stanford.

Professor Bierer’s research interests involve cochlear implants, which are prostheses that enhance or restore hearing in severely impaired individuals.  Cochlear implant patients typically perform well, but they show a wide range of speech perception abilities and most can not enjoy music.  Her research addresses the possible causes of poor outcomes and explores new clinical techniques and signal processing methods that may improve the way cochlear implant patients hear.
