We investigate geochemical and biogeochemical reactions in mineral-organic matter-water systems pertinent to Earth’s surface and near-surface regions. Exploration of molecular-scale processes responsible for limiting or enabling transport of chemical consituents in natural waters is accomplished using a variety of experimental approaches, natural materials, field samples, and advanced analytical techniques including synchrotron radiation. Current work is focused on identifying and characterizing environmental reactions involving the neurotoxic element mercury, other trace elements, and nutrient sulfur.
