Aron K. Barbey is Director of the Decision Neuroscience Laboratory at the Beckman Institute for Advanced Science and Technology at the University of Illinois. He received a Ph.D. in Psychology from Emory University in 2007 and completed a research fellowship in Cognitive Neuroscience at the National Institutes of Health in 2011. He is a member of the Beckman Institute Cognitive Neuroscience Group, the Center for Nutrition, Learning, and Memory, the Department of Bioengineering, the Department of Internal Medicine, the Department of Psychology, the Department of Speech and Hearing Science, the NeuroEngineering IGERT Program, the Neuroscience Program, and the Institute for Genomic Biology. Dr. Barbey has been praised for spearheading several of the largest and most comprehensive human lesion studies of high-level cognitive functions. He has received multiple early career academic achievement awards and won $15 million in private and federal research grants as PI since joining the University of Illinois in 2011. He is currently associate editor of Frontiers in Human Neuroscience and on the editorial board of Thinking & Reasoning and Collabra.


Aron Barbey's research investigates the principles of brain organization that underlie executive control, reasoning, and decision making. Through a combination of human behavioral, computational modeling, functional neuroimaging (fMRI), and neuropsychological patient data, we try to uncover the mechanisms that shape higher cognitive processes and to develop predictive models of brain function that link neural systems to specific patterns of inference and behavior. A central aim of our current research is to develop cognitive neuroscience directed interventions to improve higher cognitive functions, investigating the beneficial effects of cognitive, fitness, and nutritional interventions on executive control, reasoning, and decision making.
