Dr. Stevenson received his B.S. in biology from Brooklyn College of the City University of New York, and his Ph.D. in botany from the University of North Carolina at Chapel Hill.
Dr. James L. Pinckney
University of South Carolina
James L. Pinckney is a professor of marine and biological sciences at the University of South Carolina. His research interests are focused on marine ecology; microbial ecology; microalgal ecophysiology; phytoplankton-nutrient interactions; harmful algal blooms; and ecosystem eutrophication in estuarine and coastal habitats of Texas. His specific interests are centered around the ecophysiological factors and processes that influence carbon partitioning, allocation (growth), and interspecific competition in multispecies assemblages. Dr. Pinckney?s current research is being conducted in local estuarine, riverine, and intertidal habitats, as well as in pelagic systems in the Gulf of Mexico and hypersaline lagoons in the Bahamas. He received his B.S. in biology and his M.S. in marine biology from the College of Charleston, and his Ph.D. in ecology from the University of South Carolina.
Dr. Mark S. Peterson
University of Southern Mississippi
Mark S. Peterson is a professor in the Department of Coastal Sciences at the University of Southern Mississippi. His primary areas of expertise are in fisheries ecology; population biology; coastal development; habitat loss; invasive species; restoration; sustainable development; and Geographic Information Science (GIS). Dr. Peterson?s current research interests are broadly focused on habitat-use in nekton, with particular emphasis on factors affecting recruitment success and distribution in estuarine-dependent fishes and the tradeoffs made by nekton when living in different habitats. He has also recently begun addressing habitat loss and environmental variability and impacts on recruitment and distribution using GIS. He served on the NRC Committee to Review the Florida Keys Carrying Capacity Study. He received his B.S. in marine science from Coastal Carolina University, his M.S. in Bio-Environmental Oceanography, and his Ph.D. in biological sciences from the University of Southern Mississippi.
Dr. M. Siobhan Fennessy
M. Siobhan Fennessy is an assistant professor of biology at Kenyon College. Her areas of expertise are in the fields of aquatic ecology, wetland plant community dynamics, and landscape ecology. Dr. Fennessy?s primary areas of research are freshwater ecosystems, their plant communities and restoration, how ecosystems respond to human impacts, and the role of temperate wetlands in the global carbon cycle. She previously served on the faculty of the Geography Department of University College London and held a joint appointment at the Station Biologique du la Tour du Valat (located in southern France) where she conducted research on human impacts to Mediterranean wetlands. She recently co-authored book on the ecology of wetland plants. Dr. Fennessy is a 2001 recipient of the Robert J. Tomsich Science Award for excellence in scientific research. She received her B.S. in botany and Ph.D. in environmental science from the Ohio State University.
Dr. Jorge I. Restrepo
Florida Atlantic University
Jorge I. Restrepo is a professor of geohydrology and director of the Hydrological Modeling Center of the Department of Geography and Geology, Florida Atlantic University. His current research interests include evapotranspiration in southern Florida; modeling recharge, evapotranspiration, and runoff; development of a wetland simulation model; modeling of seepage in the Everglades Nutrient Removal Site Test Cells; development of a generalized computer model to represent physical and operational behavior of a stream-aquifer system for evaluating conjunctive management of surface and groundwaters; modeling the groundwater and solute transport flow for landfill areas; development of an optimization model to support the planning of a regional ASR facility along a canal system; and inferred statistical information using a hydrologic regionalization technique to infer extreme flows, average flows, and correlation structure. Dr. Restrepo served on the NRC Committee on Sustainable Underground Storage of Recoverable Water. He received his B.A. from the Universidad Nacional, Facultad de Minas, and his M.A. and Ph.D. from Colorado State University.
Dr. Ben R. Hodges
