The major goal of Dr. Valderrama’s research program is to improve the environmental and economic management of living marine resources through the application of methods derived from economic and social science. His work is largely interdisciplinary and draws from disciplines as varied as marine biology, fish ecology, and natural resource economics. Dr. Valderrama has examined the environmental and economic performance of a number of fisheries in the U.S and Latin America (Atlantic sea scallops, salmon, shrimp). In addition, he has investigated the production and environmental economics of a broad range of aquaculture species (shrimp, tilapia, catfish, hybrid striped bass, scallops, seaweed) and culture systems around the world. His research has also attempted to measure the potential of aquaculture to improve the socio-economic conditions of coastal communities affected by declining fisheries in developing countries. The accomplishment of marine conservation objectives through the development of sustainable aquaculture industries is another long-standing research interest. Dr. Valderrama has implemented his research program through academic institutions in the U.S. and Colombia, and also as an Aquaculture Officer for the Food and Agriculture Organization of the United Nations (FAO).
Dr. Valderrama’s current research projects are focused on the ecological management of the lionfish invasion in the Western Atlantic and the sustainable management of living marine resources (e.g., queen conch fishery) in the Seaflower Marine Protected Area (largest MPA in the Caribbean Sea).
Dr. Valderrama teaches both graduate and undergraduate courses in the following areas: 1) marine conservation / marine sciences; 2) environmental economics; 3) statistics / numerical analysis / experimental design. The following are some of the courses he is currently responsible for:
EVPP 421 / EVPP 521 / BIOL 450 - Marine Conservation
GEOL 309 / EVPP 309 - Introduction to Oceanography
EVPP 338 - The Economics of Environmental Policy
EVPP 651 - Multivariate Data Analysis
EVPP 692 - Seminar in Ecosystem Services
