Research in the Sensorimotor Neuroscience Lab examines how sensory information (visual, vestibular, and somatosensory) is used to control movement. This includes aspects of motor learning and adaptation, multisensory integration, and the spatiotemporal coupling of eye and limb movements. In particular, our research focuses on understanding how the nervous system integrates and uses visual input to control and to adapt walking in healthy and visually impaired individuals.
We use a combination of techniques from neurophysiology, biomechanics, and psychology to probe our research questions. Through our research we hope to (1) provide a more complete picture of the neural control of movement, and (2) discover novel strategies to improve balance and mobility, reduce falls, and increase quality of life in individuals with neurological and/or visual impairments.
