JoAnn Burkholder

JoAnn Marie Burkholder (born 1953) is an American aquatic ecologist and phycologist known for her research on nutrient pollution (cultural eutrophication), harmful algal blooms, and the biology and toxicity of the dinoflagellate genus Pfiesteria. She is William Neal Reynolds Distinguished Professor in the Department of Applied Ecology at North Carolina State University and founding director of the Center for Applied Aquatic Ecology (CAAE). Her work spans freshwater to marine ecosystems and microalgae to seagrasses, emphasizing the ecological and physiological consequences of nutrient enrichment, the behavior and toxicity of harmful algae, and the integration of science with public outreach, environmental education, and policy.
