Colin Orians, Professor of Biology and Director of Environmental Studies, is interested in global change biology, with particular emphasis on climate change, species invasion, and plant behavioral responses to herbivores. He did his graduate work in Costa Rica and views Costa Rica to be his second home. His research group at Tufts works on diverse topics, including climate impacts on coffee agroecosystems, sugar maple dynamics in New England, and the impacts of invasive species on hemlock. At Tufts he teaches courses in Global change biology, Tropical ecology and conservation, and Sustainable agriculture. He takes great joy in leading student groups to Costa Rica every other year. Every trip fills him, and his students with wonder.
