Department of Environmental Health, Science and Policy, School of Social Ecology • Taught a summer course entitled: Environmental Analysis & Design. This course was designed to fulfill the science requirement for non-science Social Ecology majors• At the time the course had no established curriculum, the school left it to the instructors to design their own course.
