Christopher Costello is Professor of Environmental and Resource Economics at the Donald Bren School of Environmental Science & Management, UC Santa Barbara. His research is primarily in the area of natural resource management and property rights under uncertainty, with a particular emphasis on information, its value, and its effect on management decisions. He is also interested in the process and design of adaptive management programs in which learning (to resolve uncertainty or asymmetric information) is actively pursued. Topical interests include fisheries management, biological diversity, introduced species, regulation of polluting industries, and marine policy. Costello frequently collaborates with researchers outside of economics such as statistics, ecology, biogeography, and mathematics.
