Isotope tracers of atmosphere, rock, water, and microbe interactions
Our interests lie in interplay among atmosphere, rock, water and microbe. We apply stable isotope systems, in particular, multiple-sulfur isotope ratios (32S/33S/34S/36S) to explore frontiers in isotope geochemistry. Our current research projects include, early microbial evolution (Archean Geochemsitry), deep biosphere, and seafloor hydrothermal deposits.
