Dr. Lee will join the Johns Hopkins Department of Neuroscience community in 2019. His laboratory research focus will be to understand brain mechanisms of decision making, in particular the role of the prefrontal cortex and basal ganglia in reinforcement learning and economic choices. His research employs diverse methods developed in economics, psychology, and neuroscience. He is also an expert in statistical modeling of behavioral and neurophysiological data. Dr. Lee received his Ph.D. from the University of Illinois at Urbana-Champaign, and postdoctoral training in neurophysiology at the University of Minnesota. Learn more about more about Dr. Lee’s neuroscience research in his TEDx Talks on “How Genes and the Brain See the World” and the "Brain and Self Intelligence".

Publications for Primary Faculty Members - December 2018:
The lab of Professor of Neuroscience James Knierim in the Zanvyl Krieger Mind/Brain Institute published a paper in Science that discovered a new role of the Lateral Entorhinal Cortex (LEC)—one of the gateways of information into the hippocampal memory system. The paper’s lead authors, Cheng Wang and Xiaojing Chen, showed that the LEC encodes experience from a first-person (egocentric) perspective, in contrast to the world-centered (allocentric) coding of place cells, grid cells, and head direction cells. This discovery supports the idea that the LEC conveys information about the sensory content of an organisms’ experience, which the hippocampus binds within the allocentric maps provided by grid cells and place cells to form the basis of an episodic memory of an event within its spatiotemporal context.
