Some of our ongoing projects:

Our group is exploring novel ways to store carbon in minerals. Mineralization is one of the ways that carbon dioxide, the primary greenhouse gas, can be removed from the atmosphere and trapped for geological time scales.

We are developing new ways to mitigate the spread of contaminants in aquifers using controlled mineral replacement reactions. These reactions can be used to create subsurface barriers that reduce groundwater flow and contaminant dispersion.

We found that pyrite grains - which often contain high concentrations of heavy metals and arsenic - become detached from rock surfaces during water-shale interaction. We are currently determining how this mechanism mobilizes contaminants in groundwater systems containing shales.

Our group is using atomic force microscopy to examine weathering mechanisms at ultra high resolution. The images show Solnhofen limestone before and after exposure to water. The dark regions are pits that form when tiny grains detach from the surface, and this is probably an important mode of limestone erosion.
