Environmental health, freshwater and marine pollutants, ecological stoichiometry, physiological ecology
My research examines how ecological factors control both the cycling of contaminants in freshwater and marine systems and human exposure to contaminants. My research interests consist of three core areas: 1) bioaccumulation of mercury and other aquatic contaminants, 2) trace metal stoichiometry in aquatic organisms and 3) human exposure to mercury and persistent organic pollutants through seafood consumption.
Currently, my work involves three main projects: 1) a large scale meta-analysis of a global database of mercury concentrations in commercial fish; 2) examining ecological drivers and temporal-spatial trends of mercury concentrations in Long Island fish; 3) investigating health effects of chronic, low-level mercury exposure through seafood consumption in Long Island adults.
