Research Interests

Coastal hydrogeology, groundwater-surface water interactions, groundwater resources, aquifer biogeochemistry

My research interests are in the subsurface component of the hydrologic cycle in coastal environments, particularly interactions between hydrology, geology, and biogeochemistry in coastal and nearshore aquifers. I also study groundwater resources under climate change and sea level rise, as well as groundwater and nutrient dynamics beneath beaches, estuaries, and bays. My research involves field experimentation and numerical groundwater flow, solute transport, and biogeochemical modeling, with a broader goal to understand fluid and chemical fluxes across the land-ocean interface.
