Harrison C. Walker, MD is a Professor of Neurology, the Medical Director for Brain Stimulation at UAB, and Vice Chair for Research for the Department of Neurosurgery – in addition to his new role as Associate Director of Neuromodulation for the CNBCI.  He received his medical degree from the University of Alabama at Birmingham in 2002 and completed a fellowship in neurophysiology at the Howard Hughes Medical Institute through the National Institutes of Health Research Scholars Program. Dr. Walker then completed his neurology residency and fellowship in movement disorders at the University of Alabama at Birmingham. His lab focuses on exploring movement pathophysiology at the systems level in humans, integrating electroencephalography, electrocorticography, local field potentials, single cell recordings, neuroimaging, and peripheral motor physiology with behavioral outcomes. Dr. Walker is currently the PI of a BRAIN Initiative study (UG3-NS130202) and a co-investigator for an NIH funded R01 grant (R01-NS119520). He has recently completed another 5-year BRAIN Initiative project (UH3-NS100553), a randomized double-blind crossover study of directional versus omnidirectional unilateral subthalamic DBS for moderately advanced Parkinson’s disease. Dr. Walker is serving as the primary mentor for NIH K-23 (K23-NS117735) awardee Nicole Bentley and for NIH K-01 (K01-DC019165) awardee Matthew Nelson. Dr. Walker has trained 8 undergraduate students, 7 medical students, 4 pre-doctoral graduate students, and mentored 5 medical residents in neurology and neurosurgery, 11 movement disorders fellows, and 4 post-doctoral fellows. Dr. Walker serves as chair of the National Institutes of Health study section NSD-C and on the editorial board of Annals of Neurology.

Dr. Kristina Visscher is an Associate Professor in the UAB Neurobiology Department. Her research focuses on plasticity of brain networks in adulthood. She and the talented members of her lab use functional magnetic resonance imaging as well as precision methods to measure behavior to examine how brain activity and connections change with experience, especially with rehabilitation after vision loss, and especially in older adults. Dr. Visscher serves as the Associate Director for Neurorehabilitation for the CNCBI, Co-Director of the Civitan International Neuroimaging Laboratory, and Associate Director of the UAB McKnight Brain Institute. Dr. Visscher is an Alabama native, having grown up in Northport Alabama, and graduated from the Alabama School of Math and Science. She became interested in the brain there, but went on to an undergraduate degree in Physics at Carleton College before switching to Neuroscience for graduate school at Washington University in St. Louis and postdocs at Brandeis University and Harvard University.
