I am interested in understanding biogeochemical cycles of other planets through application of novel isotopic tools.
I am leading a NASA-funded study on the triple-oxygen-isotope composition of sulfate minerals found in Martian meteorites. I also manage the Rice University Stable Isotope Lab, helping students and postdocs analyze stable-isotope abundances in a variety of materials.
