Environmental health, freshwater and marine pollutants, ecological stoichiometry, physiological ecology
My research examines how ecological factors control the cycling of contaminants and nutrients in freshwater and marine systems and human exposure to these nutrients and contaminants through fish consumption. 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, fatty acids 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 in avid seafood consumers.
