I am a professor of Environmental and Resource Economics at the Bren School of Environmental Science & Management, UC Santa Barbara. My research concerns natural resource management and property rights under uncertainty, with a particular emphasis on information, its value, and its effect on management decisions. My work combines theoretical work from economics with empirical analysis, often to inform policy.  My topical interests include fisheries management, biological diversity, introduced species, regulation of polluting industries, and marine policy, and I frequently collaborate with researchers outside of economics such as statistics, ecology, biogeography, and mathematics.
