Harrison Walker, MD, received his BA from Birmingham-Southern College in 1997 and his MD from the University of Alabama at Birmingham (UAB) in 2002. He completed residency and fellowship at the UAB in 2006 and 2008, respectively. As an associate professor of neurology and the medical director for surgical movement disorders at UAB, Dr. Walker supervises neurologists, residents, fellows, graduate students, medical students and nurse practitioners at one of the largest movement disorders centers in the world. Dr. Walker's long-term goal is to better understand how deep brain stimulation (DBS) changes the way the human brain works and to use this knowledge to improve clinical outcomes.  He has developed extensive methods for acquiring and analyzing biomarkers (objective measures of disease) collected from dozens of patients undergoing DBS for movement disorders using the stimulus-evoked electrocorticography (ECOG) technology. Using many sophisticated research methods, his laboratory studies how the human movement system functions in health and disease. Dr. Walker has authored 23 peer-reviewed publications in leading medical and scientific journals.
