Applied Peripheral Nervous System Neuroscience

Current Research

My particular research focuses on the decoding of afferent and efferent neuronal and muscular signals and stimulation of afferent and efferent neuronal pathways for use with neuroprostheses to restore sensory and motor function after spinal cord injury or limb loss.
