Science Advisory Board

SAB Member Martin Goldhaber

Martin Goldhaber

Senior Scientist
Powell Center Director
U.S. Geological Survey

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. 

SAB Member Jill Baron

Jill Baron

Ecosystem Ecologist
Powell Center Director
U.S. Geological Survey

Dr. Jill Baron is an ecosystem ecologist with the U.S. Geological Survey, and a Senior Research Ecologist with the Natural Resource Ecology Laboratory at Colorado State University. Her interests include applying ecosystem concepts to management of human-dominated regions, and understanding the biogeochemical and ecological effects of climate change and atmospheric nitrogen deposition to mountain ecosystems. She is co-director of the John Wesley Powell Center for Earth System Science Analysis and Synthesis.
 

SAB Member Nina Burkardt

Nina Burkardt

Research Social Scientist
U.S. Geological Survey

Dr. Nina Burkardt is a Research Social Scientist at the USGS Fort Collins Science Center. Her research focuses on negotiation and conflict resolution in natural resource decision making, institutional analysis of natural resource management processes and policies, and the use of science in decision making.
 

SAB Member Darius Semmens

Darius Semmens

Research Physical Scientist
U.S. Geological Survey Geosciences and Environmental Change Science Center

Dr. Darius Semmens is a research physical scientist at the USGS Geosciences and Environmental Change Science Center in Denver. His research focuses on modeling the spatial dynamics of ecosystem service production and flows to beneficiaries, as well as how this type of information can inform resource management. He has projects focused on mapping social value for cultural ecosystem services, quantifying the spatial ecological/economic subsidies of migratory species, and developing an integrated resource assessment framework.

Powell Center SAB member Tom Torgersen

Tom Torgersen

Program Officer
National Science Foundation

Dr. Tom Torgersen is a Program Officer at the National Science Foundation with responsibilities for Hydrologic Sciences and "Water Sustainability and Climate". His research expertise includes isotopic tracers and dating of groundwater, hydrogeology, coastal ocean processes, limnology, and paleoclimate.
Powell Center SAB member Steve Hostetler

Steve Hostetler

Research Hydrologist
U.S. Geological Survey Water Resources Division
Lake-Atmosphere Interactions Project
National Research Program
Oregon State University

Dr. Steve Hostetler has been a research scientist with the National Research Program of the US Geological Survey for the past 23 years and an Adjunct Professor, College of Earth, Ocean and Atmospheric Sciences, Oregon State University since 1996. He spent 4 years as a visiting scientist and 5 years as an affiliate scientist at the National Center for Atmospheric Research in Boulder, CO. His research project focuses on modeling past, present and future climate at global and regional scales, using climate model output to quantify interactions between the climate system and surface hydrology, glaciers, aquatic and terrestrial ecosystems and wildfire, and developing web-based tools for interactive visualization of climate model output.
Powell Center SAB member Connie Millar

Connie Millar

Chair of the Consortium
Integrated Climate Research in Western Mountains
North American chapter of the Global Observation Research Initiative in Alpine Environments (GLORIA)
USDA Forest Service

Dr. Connie Millar is a senior scientist with the USDA Forest Service, Pacific Southwest Research Station, based in Albany, California. Her research focuses on high mountain ecosystems of the Great Basin, including ecology of subalpine forests and alpine ecosystems; habitat relations of small mammals especially American pika; and thermal regimes of rocky, periglacial landforms. She has been involved in development and implementation of climate adaptation strategies for temperate forests.
Powell Center SAB member Victor Labson

Victor Labson

Director
U.S. Geological Survey Office of International Programs

Dr. Victor Labson’s career with the U.S. Geological Survey has been focused on the application of ground and airborne geophysical methods to quantitative imaging of the Earth with applications including deep crustal mapping, mineral resource appraisals, geologic hazards, environmental contamination, national security issues, and water supply development and quality. His most recent scientific focus has been on the understanding of the relationship of the chemical and physical properties of the Earth to resultant geophysical phenomena.
Powell Center SAB member Michelle Wavoord

Michelle Wavoord

Research Hydrologist
USGS National Research Program

Dr. Michelle Walvoord is a research hydrologist with the USGS National Research Program in Denver. Her area of expertise is groundwater and unsaturated zone hydrology. Her current research involves integration of hydrologic modeling, geophysics, and remote sensing.
Powell Center SAB member Dr. Kathi Irvine

Dr. Kathi Irvine

Research Statistician
Northern Rocky Mountain Science Center in Bozeman, Montana.

Dr. Kathi Irvine’s statistical research is grounded by collaborations with ecologists and biologists charged with monitoring natural resources on federal and state lands. Her projects include monitoring efforts for bats in North America (NABat), submerged aquatic vegetation on intermountain west national wildlife refuges, sagebrush steppe vegetation communities in national parks, and whitebark pine in the Greater Yellowstone Ecosystem. Her recent research involves extending statistical methods for ordinal data, applications of causal graphical models, and investigating spatial sampling designs for ecological inferences.
Powell Center SAB member Lisa Clough

Lisa Clough

Head of the Ocean Section at the U.S. National Science Foundation

Dr. Lisa Clough is an oceanographer, with much of her research focused in coastal and polar regions, and she particularly enjoys working on topics that require interdisciplinary approaches. Lisa spent 20 years at East Carolina University, achieving the rank of Full Professor of Biology, and has held positions in both Antarctic and Ocean Science at NSF.
Powell Center SAB member Dr. Steven Perakis

Dr. Steve Perakis

Research Ecologist
U.S. Geological Survey

Dr. Steve Perakis is a research ecologist with the USGS Forest and Rangeland Ecosystem Science Center, and courtesy faculty at Oregon State University. He is interested broadly in the ecological biogeochemistry of forests, grasslands, riparian and watershed ecosystems. Specific studies examine how disturbance, land-use, climate change, atmospheric deposition, plant communities, and soil development influence cycles of carbon, nitrogen and other essential elements that sustain ecosystems and society.
