Dr. Killgore is a Professor of Psychiatry, Psychology, and Medical Imaging and is the Director of the Social, Cognitive, and Affective Neuroscience (SCAN) Lab in the Department of Psychiatry at the University of Arizona College of Medicine. He is a clinical neuropsychologist and research neuroscientist whose research focuses on understanding the brain systems involved in emotional processes and cognitive performance. For the past decade, his work has focused nearly exclusively on the factors affecting the mental health, wellbeing, and performance of military personnel. His work combines neurocognitive assessment with state-of-the-art neuroimaging methods to study the role of emotion in complex cognitive processes such as moral judgment, decision-making, and risk-taking. His work also focuses on how these brain-behavior systems may be affected by environmental and lifestyle factors such as insufficient sleep, nutrition, light exposure, physical activity, and the use of stimulants such as caffeine. In particular, Dr. Killgore has explored the role of sleep as a mediator of psychological and emotional health and the potential role of insufficient sleep as a contributor to psychiatric disturbance, emotional dysregulation, risk-related behavior, and performance. He is currently conducting several Department of Defense funded studies aimed at improving sleep and resilience in military personnel. In particular, current studies focus on assessment and treatment of mild traumatic brain injury and post-traumatic stress disorder (PTSD), developing statistical models of the stress response, enhancing resilience and emotional intelligence, and improving sleep and cognitive performance through various interventions such as targeted light exposure, caffeine, and neuromodulation with transcranial magnetic stimulation.
Prior to moving to the University of Arizona in 2014, Dr. Killgore spent 17 years on the faculty at Harvard Medical School from 2000 to 2017, where he was Director of the Social, Cognitive, and Affective Neuroscience Laboratory at McLean Hospital in Belmont, MA.
Dr. Killgore also serves a Colonel in the U.S. Army Reserve, with 19 years of military service, including 5 years on active duty as an Army Research Psychologist. While stationed at the Walter Reed Army Institute of Research in Washington, DC, Dr. Killgore served as Chief of the Neurocognitive Performance Branch in the Department of Behavioral Biology.
During the course of his career, Dr. Killgore has published over 200 scientific articles and book chapters, and has co-authored over 600 published abstracts and conference proceedings with his students, advisees, and fellows. He was awarded the 2005 COL Edward L. Buescher Award for Excellence in Research by a Young Scientist, the 2010 Army Science Conference Best Paper in Neuroscience, and received a 2012 Defense Advanced Research Projects Agency (DARPA) Young Faculty Award in Neuroscience.
Dr. Killgore received his Bachelor degree in Psychology summa cum laude with distinction from the University of New Mexico, followed by a PhD in Clinical Psychology from Texas Tech University, with an internship in Clinical Psychology at Yale University School of Medicine. Dr. Killgore then completed postdoctoral fellowships in clinical neuropsychology from the University of Oklahoma Health Sciences Center and University of Pennsylvania Medical Center, and a fellowship in cognitive neuroimaging at McLean Hospital/Harvard Medical School.
