Dr. David Purcell is the Principal Investigator of the SAFER Lab. He completed his PhD at the University of Toronto specializing in otoacoustic emissions and his undergraduate and Masters degrees at the University of Waterloo. After graduate school, he had postdoctoral training at the Rotman Research Institute in Toronto specializing in auditory evoked potentials and the auditory steady-state response. Subsequently, he was a Research Associate with Queen's University in Kingston where he developed a system to study the role of auditory feedback during talking by manipulating vowel formants in real-time. Now an Associate Professor at Western in the School of Communication Sciences & Disorders and at the National Centre for Audiology, he has continued to study mechanisms of auditory feedback during speech production, the role of the olivocochlear efferent system using otoacoustic emissions, and measurement of brain activity elicited by vowel formants. He measures the brain's response to speech using envelope following responses for both basic research and validation of hearing aids in young children.
