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.

Biography

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.

Interests

I have a broad interests in the use of molecular structures and isotopic ratios of hydrogen, carbon, nitrogen, and oxygen in compound-specific organic materials from lake sediments, ocean sediments, vegetation, and meteorites. My analytical skills and understanding of organic analytical chemistry and organic geochemistry have enabled me to conduct successful research in a wide variety of fields, ranging from paleoclimatology (emphasis on continental paleoclimatology), to analytical chemistry and astrobiology. My research projects range from understanding the fundamental mechanisms and impacts of rapid climate change to the major factors that control spatial and temporal changes in C3-C4 vegetation types, as well as developing new analytical and separation techniques to study complex organic mixtures. I have established a world-class laboratory to process and measure the organic biomarkers and isotopic ratios in a wide range of samples. Major instrumentation includes, GC, GC-MS, GCIRMS, HPLC-DAD-FLD-MS.
