David J. Ostry is an engineer and neuroscientist whose research focuses on human motor control.[1][2]

He is a professor of Psychology at McGill University and a senior scientist at Haskins Laboratories in New Haven, Connecticut. His research focuses on understanding the biological mechanisms of voluntary movement and deals equally with speech production and human arm motion. He uses mathematical models, robots and behavioral and physiological techniques to assess motor function and the characteristics of motor learning. The overall goals of his work have been to understand the interplay of sensory and motor function and most recently, to understand how motor learning and adaptation affects sensory function in speech and limb movement.[3]
