Research Interests

The primary goal of my research program is to develop and implement technology to restore and enhance somatosensory function for people with amputation, spinal cord injury, mastectomy, autism, or other sensory impairments. My research focuses on somatosensation in the hand and arm, including touch, proprioception, affective (social) touch, and pain. My lab's studies aim to better understand sensory perception and sensorimotor integration and learning. We also examine the functional and psychological impacts of sensory neuroprostheses and other types of neurotechnology. My lab conducts clinical studies involving neural stimulation, neurophysiological recording, computational modeling, psychometrics, behavioral assessments, and qualitative analyses. My lab has prior and current funding from the Department of Defense, the Department of Veterans Affairs, and the Defense Advanced Research Projects Agency for our research projects.

Areas of interest: 1) Perception and processing of sensations produced by implanted medical devices, including intracortical microstimulation and peripheral nerve stimulation, 2) Development and clinical assessment of sensory neuroprostheses, 3) Neural coding of sensation, 4) User experiences with neuroprostheses and assistive technology.
