Biography
Aron K. Barbey is a professor in the Department of Psychology. He is co-chair of the Intelligence Systems research theme, leader of the Intelligence, Learning, and Plasticity Initiative, and director of the Decision Neuroscience Laboratory at the Beckman Institute for Advanced Science and Technology. He completed a research fellowship in cognitive neuroscience at the National Institutes of Health in 2011. He has won more than $25 million in federal and private research grants since joining the University of Illinois in 2011, receiving support from the National Institutes of Health (NIH), the NIH BRAIN Initiative, the Research Division of the United States Director of National Intelligence (IARPA), the Department of Defense (DARPA), the National Science Foundation (NSF), and private industry.

Research
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.
