I received my B.S. in Geochemistry from the University of Science and Technology of China in 1984, my M.S. in Analytical Chemistry from Sichuan University in 1987, a Ph.D. in Geochemistry from the Institute of Geochemistry/Chinese Academy of Sciences in 1990, and a Ph.D. in Environmental Organic Geochemistry from the University of Bristol, UK in 1997. Before coming to Brown, I worked as a Postdoc at Penn State and as a Guest Investigator at Woods Hole Oceanographic Institute. My current research interests are Organic Geochemistry, Stable Isotopes, Earth History, and Astrobiology.
