He is an aquatic ecologist who combines quantitative modeling and statistical analyses in field-based and laboratory settings to elucidate factors contributing to variability in ecological systems. Dr. Jordaan strives to unify contemporary and historical marine, estuarine and terrestrial ecology to understand productivity, nutrient, pollution, and biomass exchange between systems, and impacts they have on one another. He is particularly interested in the incorporation of historical changes and contemporary research to determine appropriate restoration goals and improve management of human activities that interact with wild fish populations.
