Models allow scientists and others to represent features and behaviors of environmental systems in order to promote inquiry, develop insight, test hypotheses, and consider solutions to problems. The class will use primary literature and hands on experiences with computer models to introduce environmentally relevant modeling tools. Topics covered will include process-based models of disease, climate, ice, ecosystems, ecosystem services, hydrology, predator-prey systems, and competition among species for resources. Students will have the opportunity to conduct original research projects either by developing their own environmental model or by using existing models. No programming experience is required. Students should have some upper level undergraduate coursework in environmental studies.science, biology, geology, physics or chemistry and be comfortable thinking quantitatively.
