I am neuroscientist and neural engineer who has dedicated my career to understanding the mechanisms underlying neural pathologies and developing treatments for these pathologies. My work has focused on restoring movement and sensory function through neural prosthetics, and utilizing neural interface technology to increase our understanding of human neural function. My lab is one of the few labs in the world that is utilizing in-vivo micro-electrode arrays to study neural function and pathology in human patients. We are acutely and chronically recording action potentials and local field potentials in both the central and peripheral nervous systems. Using this technology, we have decoded spoken words and finger movements from neural signals recorded on micro-electrode arrays implanted over language and motors areas of human cerebral cortex and studied the pathophysiology of seizure disorders. Using micro-stimulation of the primary visual cortex we have demonstrated the viability of using micro-electrodes as the basis for a visual prosthesis for restoring limited vision in the profoundly blind. We have decoded finger movements and provided sensory feedback using micro-electrode arrays implanted in the residual peripheral nerves of patients with an amputation. Currently, my lab is collaborating with neurologists and neurosurgeons at the Barrow Neurological Institute to study and improve treatments for Parkinson’s Disease. We are using arrays of micro-electrodes to examine the neural dynamics in the cortico-basal ganglia network during Deep Brain Stimulation.
