Research Interests: 

As a physician-scientist in the Department of Pathology and Laboratory Medicine and The Saban Research Institute, Tian conducts translational neuroscience research in the field of neurodevelopmental disorders (NDDs) using in vivo models and multidisciplinary approaches. The Tian Laboratory is interested in generating novel in vivo models of NDDs using genome editing technology; understanding the mechanism by which common and rare genetic abnormalities contribute to these disorders; and studying how epigenetic genes regulate brain development and functions. He employs a variety of experimental approaches, including genetics, biochemistry, electrophysiology, and behavioral analyses. His ultimate goal is to find the mechanisms for certain types of neurodevelopment disorders and to identify therapeutic targets.
