Timothy S. Griffin is an associate professor in the Friedman School of Nutrition Science and Policy of Tufts University. He directs the interdisciplinary graduate program Agriculture, Food and the Environment and teaches classes on U.S. agriculture, agricultural science and policy, and the intersection of ecology and technology. He also serves on the steering committee for the university-wide graduate program Water: Systems, Science and Society and is a faculty codirector of the Tufts Institute for the Environment, and is a faculty affiliate at the Center for International Environment and Resource Policy at Tufts. His current research focuses on barriers to and incentives for regional food systems, environmental effects of agriculture, climate change, and conservation practices in agricultural systems. Before coming to the Friedman School in 2008, Dr. Griffin was research agronomist and lead scientist with the U.S. Department of Agriculture Agricultural Research Service in Orono, Maine, from 2000 to 2008. He conducted research on many aspects of agricultural production in the northeastern United States, including nutrient cycling and grain production on organic dairy farms, crop management, and long-term sustainability of high-value production systems. He also initiated research on greenhouse-gas emissions, soil carbon and nitrogen cycling, and soil conservation in these systems. From 1992 to 2000, Dr. Griffin was an extension sustainable agriculture specialist with the University of Maine, the first such position in the United States. He developed and delivered a wide-ranging educational and applied-research program on crop production, nutrient availability, and crop–livestock integration. He received his BS in forage and range management and his MS in agronomy from the University of Nebraska and his PhD in crop and soil science from Michigan State University.
