Winrock Team

Dr. Sandra Brown, Senior Scientist, Ecosystem Services Unit, Winrock International

Dr. Sandra Brown is a specialist in the role of land use and land cover change in the global carbon cycle and climate change, the impacts of climate change on terrestrial ecosystems, and the present and potential future role of terrestrial ecosystems for mitigation of climate change. In her more than 26 years of project experience, she has successfully led over 40 projects, providing leadership and expertise to many national and international organizations in the field of land use/land cover change and its relation to climate change and mitigation. She has published more than 190 peer-reviewed publications in scientific journals and books, and has served as a co-convening lead author for five UNFCCC IPCC Reports. Dr. Brown holds a Ph.D. in systems ecology from the Department of Environmental Engineering Sciences, University of Florida, Gainesville, a MS. in engineering science from the University of South Florida, Tampa, and a BSc. in chemistry from the University of Nottingham, England.

Dr. Stephen Hagen, Senior Scientist, Applied Geosolutions, LLC

Dr. Stephen C. Hagen is a project leader with a focus on the use of models and data mining techniques to extract information about the land surface and physical processes from large geospatial datasets, particularly remote sensing data. A key component of this work includes the estimation of uncertainty involved in modeling physical systems. Dr. Hagen has led several NASA- and USDA- funded projects aimed primarily at mapping and monitoring rangelands, savannas, and forests. Dr. Hagen holds a Ph.D. in Earth and Environmental Science from The University of New Hampshire, and an M.S and a B.S. in Systems Engineering from the University of Virginia.

Dr. Nancy Harris, Senior Carbon and Land Use Specialist, Ecosystem Services Group Unit, Winrock International

Dr. Nancy Harris is a carbon specialist with over seven years of experience in climate change and land use and is an expert in the analysis and assessment of changes in carbon stocks and flows in the land use and forestry sector. She has worked in the U.S. and throughout the world to provide technical assistance on carbon sequestration and emission avoidance projects, and helped develop the Voluntary Carbon Standard for avoided emissions projects. Dr. Harris has published several peer-reviewed papers on carbon measurement, monitoring and modeling. Dr. Harris holds a PhD in systems ecology from SUNY College of Environmental Science and Forestry and a bachelor’s degree in Biology and Environmental Studies from Tufts University.

Woods Hole Team

Dr. Alessandro Baccini, Assistant Scientist, Woods Hole Research Center

Dr. Alessandro Baccini is a remote sensing scientist whose interests focus on the use of satellite data for the monitoring of forest carbon, land cover, land cover change and the effects of environmental change on the terrestrial carbon cycle at the regional and global scale. Before joining the Center he was a research associate at Boston University and worked at the Food and Agriculture Organization of United Nations for the Forest Resources Assessment 1990 and 2000 monitoring tropical deforestation. Dr. Baccini received his bachelor’s and master’s degrees in Forest Sciences from the University of Florence, and received his PhD in Geography and Environment from Boston University.

Dr. Richard A. Houghton, Senior Scientist, Woods Hole Research Center

Dr. Houghton is an ecologist with interests in the role that terrestrial ecosystems play in climate change and the global carbon cycle. He co-ordinates the Center’s efforts to understand the problems of global warming and climate change, especially the role biotic systems play in this accelerating process. His area of expertise has been documentation of changes in land use and determination of historic and current sources and sinks of carbon resulting directly from human activity. Dr. Houghton has held positions as Assistant Scientist at the Ecosystems Center of the Marine Biological Laboratory and as Research Associate at Brookhaven National Laboratory. He earned his doctorate in ecology from SUNY at Stony Brook.
