The Environmental Geochemistry Group addresses fundamental geochemical questions regarding what controls mineral-fluid interactions, particularly mineral dissolution-precipitation reactions. Mineral-fluid interactions have important implications for understanding natural mineral weathering and element cycling processes over geologic time, and influence issues of immediate environmental significance such as groundwater contamination, nutrient availability, and engineered CO2 capture and storage under a changing environment. We use a variety of techniques including experiments, isotopic and mineral analyses, and geochemical and reactive transport modelling approaches, complemented by field data.
Some current research projects include:
- Mechanisms of gas-driven mineral weathering in a changing climate (SERI-funded ERC Starting Grant)
- Developing sustainable CO2 removal technologies,
- Mechanisms of isotope exchange during water-rock interaction.
Motivated students and researchers are encouraged to get in touch to discuss research opportunities in our group.
