I obtained my Ph.D. at the department of Biochemistry at University of Illinois at Urbana-Champaign in 2006. During 2001-2006, I worked with my mentor Dr. Scott K. Silverman studying deoxyribozymes that catalyze the ligation of RNA molecules. Then I moved to University of California at San Francisco to conduct my post-doctoral research on stem cells and miRNAs with Dr. Robert H. Blelloch. I started my own laboratory at Peking University in 2011. My interest is to understand molecular mechanisms that control the self-renewal and differentiation of stem cells. I am particularly interested in microRNAs, long noncoding RNAs and RNA binding proteins.
