We study the physical and chemical evolution of the Earth's surface: today and in the geologic past. 

In ESG, our goal is to refine concepts of element cycles on Earth (namely the carbon cycle) by making high-quality geochemical measurements of Earth materials, such as soil, water, rock, and organic matter, and building mathematical models that link these measurements with processes that shape ecosystems and impact climate. Key knowledge gaps we aim to address include the movement of water and sediment across landscapes, the formation of clay minerals, the influence of the biosphere on surface processes, and the fidelity of the geologic record.

Fostering a diverse and inclusive community, broadly disseminating our work, and making the daily process of discovery fun are as important as our research aims.
