Research Interests
Neural interfaces; Neuromodulation; rehabilitation of walking; reinforcement learning; sensorimotor controlDr. Dalrymple is the Director of the Neural Engineering and Rehabilitation Via Electrical Stimulation (NERVES) Lab. The NERVES Lab is an interdisciplinary research lab focused on using electrical stimulation to improve sensorimotor function after neural injury. They combine concepts from engineering, neuroscience, computing science, and rehabilitation to provide solutions to improve walking, restore sensation, and reduce pain in both preclinical and clinical studies.
See Dr. Dalrymple’s website for more information.
