Karen Gordon, PhD, is an Associate Professor in the Department of Otolaryngology and a Graduate Faculty Member in the Institute of Medical Science at the University of Toronto. She works at the Hospital for Sick Children in Toronto, Ontario, Canada, as a Senior Scientist in the Research Institute and an Audiologist in the Department of Communication Disorders. She is Director of Research in Archie’s Cochlear Implant Laboratory and holds the Bastable-Potts Health Clinician Scientist Award in Hearing Impairment. Karen’s research focuses on auditory development in children who are deaf and use auditory prostheses including cochlear implants. Her early work examined the role of a unilateral cochlear implant to promote plasticity in the auditory nerve, brainstem, thalamus and cortex in children with early onset deafness. More recently, she has been interested in reorganization resulting from unilateral hearing from early childhood including changes in bilateral auditory pathways and effects on binaural hearing. Karen has been awarded grant funding for her work on auditory development in children using bilateral cochlear implants and bimodal prostheses (a hearing aid in one ear and a cochlear implant in the other) from both the Canadian Institutes for Health Research and the SickKids Foundation.
