The Powell Center Science Advisory Board (SAB) reviews proposals and makes recommendations to the Directors who make the final decisions about which proposals to support. SAB members may not be subject matter experts; write proposals that are understandable and compelling to non-specialists.

Senior Scientist Emirates 
Powell Center Director
U.S. Geological Survey

Dr. Marty Goldhaber is geochemist and currently a Senior Scientist at the USGS where he received the Department of the Interior Meritorious Service and Presidential Rank Awards. He has served a rotation as the Chief Scientist for Geology and has also served as co-chair of the USGS Science Strategy Team which was charged with defining key strategic directions for the USGS. His current research is on the evolution of the broad ‘geochemical landscapes’ resulting from the interplay of geologic, geomorphologic, hydrologic, and biologic processes. Geochemical landscape studies are underway in the Sacramento Valley of California, and the Prairie Pothole region of the north central U.S. and southern Canada.

Dr. Laura Lautz is a Program Director in the Hydrologic Sciences Program in the Directorate of Geosciences’ Earth Science Division at the National Science Foundation. Prior to her arrival at NSF, she was the Jessie Page Heroy Professor and Department Chair of Earth Sciences at Syracuse University. Her research addresses how hydrologic processes influence water quality and movement through watersheds, with particular emphasis on how water and solutes move through paired surface and groundwater systems, heat tracing, and the nexus of water and energy systems.

Dr. John Bradford
Research Ecologist
U.S. Geological Survey 

Dr. John Bradford is a research scientist with the United States Geological Survey, located in Flagstaff, Arizona.  He works to understand the influence of ecological drought on dryland vegetation and engage with natural resource managers to develop appropriate management strategies for a changing climate.  John’s research integrates simulation models with ecological data to quantify detailed patterns of drought and assess drought impacts on vegetation. This involves identifying the drought and moisture conditions that determine vegetation structure, function and composition, assessing patterns of those conditions across space and time, and evaluating the implications of future shifts in those conditions. Increasingly in recent years, John synthesizes these and other research results to help land managers anticipate the long-term impacts of climate change on their vegetation resources.

Dr. Gary A. Lamberti
U.S. National Science Foundation

Dr. Gary A. Lamberti is currently a rotating program officer in the Division of Environmental Biology at the National Science Foundation. Dr. Lamberti’s home institution is the University of Notre Dame where he is Professor of Biological Sciences and Director of the Stream and Wetland Ecology Laboratory (SWEL). His major research interests include (1) linkages among aquatic ecosystems; (2) the ecology of native and introduced Pacific salmon; and (3) the impacts of global change on aquatic ecosystem function. Dr. Lamberti conducts his research in Alaska and around the Laurentian Great Lakes. In Alaska, he investigates the cycling of salmon-derived nutrients in freshwater and riparian ecosystems. Around the Great Lakes, he studies the unintended consequences of past introductions of Pacific salmon, which can transport contaminants to new areas during their spawning migrations. His laboratory also investigates the ecology of deltaic wetlands in Alaska and coastal wetlands of the Great Lakes, with the objective of understanding the function of these vital ecosystems under global change. He has successfully mentored 30 M.S. and Ph.D. students to completion and countless undergraduates have conducted research in his laboratory. Dr. Lamberti has over 200 publications dealing with various aspects of aquatic ecology, and has co-edited the Elsevier book entitled Methods in Stream Ecology, now in its 3rd edition. Dr. Lamberti is a Fellow of the American Association for the Advancement of Science and a Fellow and past-President of the Society for Freshwater Science, an international society of aquatic ecologists.
