Research Interests

We use various forms of gene targeting in mouse embryonic stem cells to generate genetically engineered mouse lines. One major focus of our lab is to use these mutant mice as animal models for human diseases, which allows us to study the molecular mechanism of diseases in vivo. In addition, we are beginning to explore the role of DNA methylation-dependent epigenetic regulatory mechanism in adult neurogenesis. Most recently, we have generated disease-specific induced pluripotent stem (iPS) cells from several Rett syndrome (RTT) patients. We plan to use these RTT iPS cells as a tissue culture based human model of the disease for understanding its pathogenesis and screening for drugs.
