- Our interests lie in interplay among atmosphere, rock, water and microbe. We apply stable isotope systems, in particular, multiple-sulfur isotope ratios to explore frontiers in isotope geochemistry. Our current research projects include, photochemical sulfur isotope effect, early microbial evolution, deep biosphere, and seafloor hydrothermal deposits. In addition, new project is starting under the NSF-MRI support to develop the state-of-the-art instrument for isotopomer monitoring of atmospheric nitrous oxide (with Ron Prinn of EPAS and Center of Global Change Science). Interested students are encouraged to inquire about potential research projects in the laboratory.
