Xiaoxi Zhuang, PhD's main interest in science is the neurobiological basis of behavior. This interest started in his college years in Beijing University (1984-1988) where he double majored in biophysics and psychology. This interest was further strengthened during his PhD training in biopsychology at Columbia University from 1991 to 1996. He began his postdoctoral training with Rene Hen at the Center for Neurobiology and Behavior of Columbia University in 1996, where he developed expertise in sophisticated genetics, and most importantly, learned to use genetic approaches to examine the neurobiological basis of behavior. Zhuang joined the Department of Neurobiology, The University of Chicago in 2001 as an assistant professor and was promoted to associate professor in 2007. His research group focuses on the role of dopamine in modulating behavior (motor learning and performance; reward based learning and motivation; foraging strategy, fitness and obesity) using genetic approaches. These studies have led to funding from the NIH, NARSAD, the National Alliance for Autism Research, the Edward Mallinckrodt, Jr. Foundation, the Tourette Syndrome Association, Brain Research Foundation, the National Parkinson Foundation, the Parkinson's Disease Foundation, the American Parkinson Disease Association, and The Michael J. Fox Foundation for Parkinson’s Research.
