Brief Biography

Dr. Blake Papsin an associate scientist in the Neurosciences & Mental Health program and has served as a paediatric otolaryngologist at The Hospital for Sick Children since July 1996 and is also a professor in the Department of Otolaryngology at the University of Toronto. Papsin trained in otolaryngology at the University of Toronto and also completed a paediatric otolaryngology Fellowship at Great Ormond Street Hospital for Children in London, England. He has a MSc in Psychoacoustics and has done research in this field. Papsin is the inaugural chair of the Cochlear Americas Chair in Auditory Development at the University of Toronto.

Papsin’s clinical focus is the surgical rehabilitation of hearing loss, and he is the Director of the Cochlear Implant Program in addition to running the bone-anchored hearing aid and auricular prosthesis programs.

Papsin also runs a laboratory which is currently focused on the growth and development of the auditory system after cochlear implantation. He holds three grants, has published 104 peer-reviewed journal articles, 23 book chapters and has spoken widely on the subject of surgical rehabilitation of hearing loss. Papsin feels fortunate to have begun his clinical practice at a time when the auditory neuroprosthetic became available clinically.

Research Interests

Auditory system development after cochlear implantation

Research Activities

Research in my lab is directed at determining how the auditory system develops after cochlear implantation in young children, we examine the auditory system using electrophysiologic measurements and compare the time course of development with the known rates of development for persons with normal hearing. In addition, we analyze speech and language outcomes to identify the optimal time for cochlear implantation and possible factors that might predict superior performance.
