Mark Lubell is Professor in the Department of Environmental Science and Policy at the University of California, Davis and the Director of its Center for Environmental Policy and Behavior. Lubell studies cooperation problems and decision making in environmental, agricultural, and public policy. Through application of social science theory and research methods, Lubell uses his work to provide practical results and recommendations to real policy and decision makers. His research topics include water management, sustainable agriculture, adaptive decision-making, climate change policy, local government policy, transportation behavior, plant disease management, invasive species, and policy/social network analysis. Following a natural science model of scientific inquiry, his long-term research agenda is to discover common principles of cooperation that can be observed and tested in all three modes of research: theory, experiment, and field.
