Research Group
Cameron Donofrio is a M.S. student in the Ecotoxicology program within the Stokes School of Marine and Environmental Sciences at the University of South Alabama. He received a B.S. in Marine Biology from the University of West Florida in 2022. Cameron is interested in coastal eutrophication and the impacts of nutrient cycling on coastal water quality and is working on a collaborative project with the Grand Bay National Estuarine Research Reserve.
