Daeyeol Lee is a professor of neurobiology and psychology at Yale University and the director of Yale laboratory of cognition and decision making. Dr. Lee received his bachelor’s degree in Economics from Seoul National University in Korea and his PhD in Neuroscience from the University of Illinois at Urbana-Champaign. He then received a postdoctoral training in neurophysiology at the University of Minnesota. His current research focuses on the brain mechanisms of decision making, in particular the role of the prefrontal cortex and basal ganglia in reinforcement learning and economic choices. His research is highly interdisciplinary, combining diverse methods developed in economics, psychology, and neuroscience. He is also an expert in statistical modeling of behavioral and neurophysiological data. He has published over 70 original research articles, including several papers in Science, Nature Neuroscience, and Neuron. He was the recipient of the Fellowship for Prominent Collegians from Korea Foundation for Advanced Studies, University Fellowship from the University of Illinois, and the James S. McDonnell Foundation Cognitive Neuroscience Grant. His research has been funded by the National Institute of Health continuously since 1999.
