Current Research

The goal of my research is to help people with neurologic disorders, especially those who are severely paralyzed from stroke, spinal cord injury, cerebral palsy, or ALS. Our research centers around using neural prosthetics, i.e., human machine interfaces, to help restore or replace function of the injured nervous system. We study brain-machine interfaces in monkeys and humans, allowing them to control a computer cursor or virtual hand directly from their brain signals. These signals are obtained via electrodes implanted in or on the surface of the brain or dura mater. In addition, we are investigating the potential to decode a person’s intended speech directly from his or her brain and using this to restore communication to people who have lost it due to severe paralysis. We also use this powerful paradigm to study the underlying relationship between different types of brain signals, for example, the relationship between field potentials (summed from many neurons in the network) and action potentials of individual neurons. Finally, we are developing a myoelectric computer interface to help survivors of stroke regain function in their arms.
