I am a Research Associate working with the Biogeochemistry of Global Contaminants group in the School of Engineering and Applied Sciences. My research is the development of numerical models to study how biogeochemical processes affect the fate, transport and food-web bioaccumulation of trace metals and organic chemicals in the environment and marine ecosystems. In particular, I am actively working on the biogeochemistry of mercury, the food-web bioaccumulation of mercury, and the fate and transport of perfluoroalkyl substances (PFAS).
