Paleoclimate, Weathering & Paleohydrology
Our research in the area of paleoclimate focuses on two key aspects for understanding the evolution of Earth's surface and climate over time: (1) the role of chemical weathering processes in regulating the geologic carbon cycle over million-year time scales, and (2) soil water infiltration over thousand-year or glacial-interglacial time scales.
Our research in this area determines how chemical reactions between fluids and solids may attenuate, or exacerbate, groundwater contamination. We are currently focusing on several different types of contaminants, including metals and actinides/radionuclides.
Geologic Carbon Storage (GCS)
The injection of large volumes of CO2 into the subsurface is an essential strategy for both enhanced energy extraction and the disposal of waste products derived from energy generation.
