The Systems option is designed for students who want to emphasize problem solving methods and applications rather than a particular topical area in environmental science. A quantitative holistic approach in analysis of environmental problems is emphasized. Students in this option follow the general curriculum for the Environmental Science M.S. degree but are encouraged to take additional courses in quantitative problem solving. Each student is strongly encouraged to prepare a thesis. Current subjects that match faculty research interests include risk assessment, project evaluation, facility sitting, hazardous waste disposal, and energy- environment interactions.
