- Water-rock interaction in the redox-active subsurface with connections to water resources, public health, and energy production (arsenic and other natural water contaminants, biogenic methane, stable isotopes…)
- Groundwater in Piedmont watersheds, urbanization, and critical zone processes (stream restoration, weathering and watersheds at Redlair Observatory…)
Environments of interest range from urban streams to deep saline groundwater. As tools, I use natural elements and isotope fingerprints to trace processes such as water-rock interaction, biogeochemical reactions, and mixing. My research program is highly interdisciplinary, and currently involves collaboration with colleagues in soil science, environmental engineering, geospatial science, and geomicrobiology.
At UNC Charlotte, I teach courses in earth science, geochemistry, hydrology, and hydrogeology. My research group includes undergraduates, master’s, and doctoral students (see recent thesis topics).
