I am a physical hydrogeologist interested in how environmental variability affects water flowing on and through the earth in terrestrial and marine settings--especially how moving water (like waves and currents) and climate drive groundwater flow and chemistry in coastal and marine aquifers. I also study the potential interactions between climate change and the quantity and quality of groundwater in aquifers. My research uses a combination of field, laboratory, and numerical modeling techniques to address these questions, and I amplify my reach through collaborations with engineers, biogeochemists and geophysicists. The resulting work covers scales from centimeters-to-globe and seconds-to-centuries with implications for estimating the availability of groundwater resources, fluid and chemical fluxes to the ocean, and understanding the global impacts of a changing climate.
