Biography
My research focuses on contaminant transport in the environment which is affected by a range of phenomena occurring at the mineral-water interface. Our research draws from mineralogy and biogeochemistry and intersects with hydrology-hydrogeology to produce a more unified understanding of contaminant transport through complex materials across a wide range of spatial regimes. The research group focuses on: (1) Characterization and analysis of natural mineral surface coatings and associated metal(loid)s, and (2) Interdisciplinary field-based studies of mineral surface reactivity, metal(loid) transport, and geochemical cycling. Our work is accomplished by integrating field-based studies with laboratory-based analytical techniques, and synchrotron-based X-ray spectroscopic and scattering methods to investigate natural and model systems. Current work focuses on: (1) Lead (Pb) contamination in urban soils; and (2) Metal(loid) transport, soil formation, and contaminant in watersheds impacted by historic coal mining in Appalachia.
