Biography
I am a biogeochemist and sedimentary geologist whose research centers on terrestrial environments, with a particular focus on modern soils and paleosols (fossil soils). I employ a combined observational and experimental approach that incorporates physical, elemental, and isotopic data collected in the field and laboratory. The ultimate goal of my research is to understand how terrestrial environments will respond to anthropogenic-driven climate change and how they have changed throughout Earth History.
