Tongwei Zhang Email: zhangtw@peer.caltech.edu Education: -Ph.D., Isotope Geochemistry, Chinese Academy of Sciences -M.S., Petroleum Geochemistry, Chinese Academy of Sciences -B.S., Petroleum and Natural Gas Geology, Northwest University, China Research Interests: Starting from September of 2001, He has been working as a postdoctoral scholar at PEER Center, Caltech. His current research project is Thermochemical Sulfate Reduction (TSR) mechanism and its kinetics. His research interest is to quantitatively make the expression of geological processes in sedimentary basin by widely integrating geological observations, geochemistry data and experimental simulation results. The research areas are covering in sedimentary petroleum geology, isotope geochemistry, laboratory's experimental simulation, kinetics of hydrocarbons generation, hydrocarbon migration modeling and basin modeling. He contributed about 30 publications in above areas. Selected Publications: -Zhang Tongwei and Bernhard Krooss (2001).
