I specialize in the development and application of organic isotope geochemistry and organic analytical chemistry to problems in the environment, paleoclimate, paleohydrology, and astrobiology. My goal is to create new approaches and applying these approaches to understanding mechanisms and solving prominent problems in continental climatic change, environmental response to climate change, analysis and separation of complex organic mixtures and in astrobiology.
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 the Chengdu University of Science and Technology of China 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.
