Our research laboratory focuses on innovating neuromodulation technologies to improve quality of life for people with neurological disorders. Deep brain stimulation (DBS) is one such technology, which has helped numerous people living with Parkinson's disease, dystonia, and essential tremor reclaim control over their motor function. DBS therapy involves placing tiny electrodes in regions of the brain that exhibit pathological activity and then stimulating those regions with continuous pulses of energy. We focus on understanding how the brain responds and adapts to stimulation-based therapies from a combination of computational and experimental perspectives. These studies in turn provide us with a rationale to develop, evaluate, and translate new approaches for improving patient care.
