Roxanne Karimi’s research examines how ecological factors influence the cycling of nutrients and contaminants in freshwater and marine ecosystems, and human exposure to these nutrients and contaminants through fish consumption. Her research interests consist of three core areas: 1) mercury bioaccumulation and transfer through the food web, 2) element patterns in aquatic organisms 3) human health effects from exposure to mercury, fatty acids, and other substances through seafood consumption.
