    Current Research and Scholarly Interests I study the motor system (how our brain plans, generates, and corrects movements) and apply this science to translational efforts to develop of motor neural prostheses that can restore movement to people with paralysis. My Ph.D. research spanned both fundamental motor neuroscience and applied neural engineering.

    On the basic science side, I investigated 1) how "internal models" of how the brain's output effects the arm are used by motor cortex. 2) how sensory information carrying information about movement errors is prevented from interfering with motor cortical output until it is "ready" to generate the appropriate output; and 3) how the dynamical rules governing motor cortical activity restrict the kinds of outputs it can generate for the purpose of commanding a neural prosthesis.

    My pre-clinical neural engineering research focused on 1) how to robustly decode a user's intended movement despite minute-by-minute and day-to-day changes in neural signals, and 2) sensors' gradually losing the ability to record neuronal action potential. I also studied (3) the effect of ongoing sensory feedback on this signal, and how we can exploit this information to detect and automatically correct for errors.

    My current postdoctoral research focuses on provided people with paralysis who are enrolled in our neural prosthesis clinical trial with the ability to accurately control a robotic arm and hand.
