I am an Associate Professor with a joint appointment between the Department of Geosciences and Commonwealth Honors College. My main research interests lie in utilizing organic geochemical and isotopic proxies to examine past climates and past environments. My research interests include: paleoclimate, paleoceanography, organic biogeochemistry, paleolimnology and limnology, stable isotope geochemistry, biogeochemical cycles, anthropogenic impacts on the environment, climate variability and hominin evolution. I am also interested in developing and improving proxies for reconstructing past environmental conditions.
