• Water-rock interaction in the redox-sensitive subsurface (arsenic, chromium, vanadium, strontium isotopes, radium isotopes)
• The role of shallow groundwater in Piedmont weathering, watersheds, and critical zone processes (stream restoration, urban dissolved inorganic carbon, water at the Redlair Observatory…)
• Subsurface biogeochemistry (methanogenesis, stable isotopes…)

I examine the processes that control element occurrence in natural and human-modified waters, with applications to energy resources, water quality, and groundwater sustainability. Environments of interest range from urban streams to deep saline groundwater. As tools, I use natural elements and isotope fingerprints to trace water-rock interaction, biogeochemical processing, mixing, and movement. These tools are combined with physical hydrologic data and in some cases microbiology to address a range of interdisciplinary problems. At UNC Charlotte, I teach courses in earth science, geochemistry, hydrology, and hydrogeology.
