Dr. Xu obtained Ph.D. at University of Southern California in 2008, where he worked with Dr. Michel Baudry studying the interaction between glutamate receptors and calpain and its implications in brain functions. He then conducted postdoctoral research with Dr. Tom Südhof at HHMI and Stanford University where he started to develop molecular tools for exploring brain circuits and used the tools to address questions related to memory. He joined the department of Neuroscience at UT Southwestern in Dec. 2014.
Dr. Xu is interested in the neuronal mechanisms underlying the basic cognitive processes. He focuses on the circuit level with the goal of bridging cellular and synaptic phenomena to high-level brain functions. The specific questions include the encoding, retrieval and generalization of memories and the brain’s executive control over the selection of behavioral programs.
