I am a Professor of Psychiatry and of Neuroscience at Yale University School of Medicine. I graduated from National Taiwan University College of Medicine and California Institute of Technology and has been a faculty member at Yale since 2003. My earlier work employed non-human primate models to understand the neural bases of cognition. Current research in my laboratory continues to focus on systems neuroscience. By combining psychophysics, computational modeling and brain imaging we explore the circuit mechanisms of a multitude of cognitive constructs, including self control, affect regulation, and reward-related processes. The primary goals are to understand systems neural bases of these cognitive processes and how these neural processes contribute to the etiology of psychiatric and neurological illnesses, with a specific emphasis on addiction.
