Our research is in the area of neural engineering: using engineering techniques to understand and control neural function. We work primarily on fundamental questions related to neural prostheses. Neural prostheses are a developing technology that uses electrical activation of the nervous system to restore function to individuals with neurological impairment. The long-term goal of our research program is to develop advanced neural prostheses that interface with the central nervous system (brain and spinal cord) to restore function.

Current projects include electrical stimulation for restoration of bladder function, deep brain stimulation for treatment of motor disorders, electrical stimulation for restoration of multi-joint motor function (e.g., reaching), and design of novel electrodes and waveforms for selective stimulation of the nervous system.
