Overview


I am a surgeon-scientist specialized in the treatment of epilepsy and movement disorders.  My laboratory conducts basic and translational neuroscience research on cortical inhibitory circuits.  We are interested in 1) understanding the cellular design of inhibitory circuits in mice and humans, and, 2) advancing interneuron transplantation as a therapeutic strategy for inhibitory circuit repair.
