David Ostry

David J. Ostry [1][2] is an engineer and neuroscientist whose research focuses on human motor control. He is a professor of Psychology at McGill University and a senior scientist at Haskins Laboratories in New Haven, Connecticut. His areas of expertise include motor control and motor learning, speech production and biomechanical modeling. His research at Haskins Laboratories focuses on somatosensory function in speech. The aim is to understand how somatosensory inputs are used in both speech learning and control and to assess their possible influences on speech perception.[3]
