I am an Organic and Stable Isotope Geochemist, Geobiologist, and Sedimentary Geologist

I specialize in the measurement and analysis of Carbon and Nitrogen isotope ratios in organic archives, lipid biomarkers, the nutrient dynamics of stratified aquatic basins, and the evolution of the C, N, and S cycles throughout Earth’s History. Currently working on P and methane cycling in subtropical pasturelands.
