Bradley Barth is a PhD candidate in the Shen laboratory at Duke University. He studies the neural control of motility in the gastrointestinal system with in vivo electrophysiology and electrical stimulation. Bradley develops new devices and techniques to assess function and disease in the gut. He then builds predictive computational models of neuromuscular motility and applies these predictive models to improve neuromodulation therapies for functional gastrointestinal disorders.
