His research group develops and applies novel isotope proxies to trace the evolution of geochemical cycles and the interplay between microbes and geochemistry. Recent research topics include application of tunable laser spectroscopy for precise measurements of clumped methane isotopologues. His past service to the Geochemical Society includes the Clarke Award Committee, Editor for Geochemical News, and International Liaison for Goldschmidt 2016. He is a co-chair for Goldschmidt 2018.
