I am interested in using isotope signatures, especially tools like clumped isotopes, to resolve the provenance of methane gases. My goal is to combine lab incubation and modeling to understand the mechanism of clumped isotope fractionation in methanogenesis and methane oxidation. My research are mainly in the field of biogeochemistry, stable isotope and clumped isotopes.

I'm interested in the way that microbes drive Earth's biogeochemical cycles, and are in turn influenced by their environments.  I find questions about life origins as well as the evolution of microbial metabolism fascinating.  At Dartmouth I am excited to study the relationships between archaeal lipid cyclization and environmental conditions among thermoacidophiles.  In the future, I hope to continue to explore the limits of microbial life in Earth's unique ecosystems.
