Wendy Baldwin, Population Council
Wendy Baldwin, began serving as Presdient and CEO of the Population Reference Bureau in June 2011. Prior to joining the PRB, she served as vice president and director of the Poverty, Gender, and Youth program at the Population Council, where she worked with the council's regional directors and professional staff to implement program- and policy-oriented research to improve the future of young people in developing countries. For the past 20 years she has worked with the World Health Organization, serving since 1988 as the chair and collaborating scientist of the Steering Committee on Behavioral and Social Science Research on Reproductive Health.
Daniel Brown, University of Michigan
Daniel Brown’s research focuses on linking landscape patterns with ecological and social processes. His particular focus is on land-use and land-cover dynamics, making use of multiple methods, including GIS, remote sensing, digital terrain analysis, ecological mapping, social surveys and statistics, and computer simulation. Specific projects focus on the interacting social and ecological aspects of land use and cover change in rural and peri-urban environments, land use and vulnerability to flooding in China, and spatial and social effects on health.
Janet Gornick, City University of New York
Janet Gornick is currently Professor of Political Science and Sociology at the Graduate Center of the City University of New York (CUNY). She is also Director of the Luxembourg Income Study (LIS), a cross-national data archive and research center located in Luxembourg.

Reeve Vanneman, University of Maryland
Reeve Vanneman is a stratification sociologist whose recent research focuses on changing gender inequalities in the United States and India. He is working with Dave Cotter and Joan Hermsen, to understand why the U.S. gender revolution of the 1970s and 1980s seems to have come to a halt in the 1990s. With Sonal Desai and colleagues in Delhi at the National Council of Applied Economic Research, Reeve helped field a nationwide survey in India of 41,554 households. This panel survey analyzes the relationships of poverty, gender stratification, and social capital on health and education outcomes.
Stephen Walsh, University of North Carolina
Stephen Walsh is Professor of Geography, member of the Ecology Curriculum, and Research Fellow of the Carolina Population Center at the University of North Carolina, Chapel Hill. Broadly speaking, his research seeks to understand ecological, biogeographic, and geomorphic factors affecting landscape patterns at a host of space and time scales. Several projects examine coupled human-natural systems and land use/cover dynamics in the frontier environment of the Northern Ecuadorian Amazon, the Galapagos Islands, and in rural Nang Rong District, Northeastern Thailand. The transformation of the Earth’s surface in these regions, particularly through deforestation, agricultural extensification, secondary forest succession, and urbanization, is linked to a variety of scientific and policy issues revolving around the human dimensions of land use/cover change and the proximate and distal causes and consequences of such changes. Additional research emphasizes pattern-process relationships at the alpine and sub-alpine environments of Glacier National Park, Montana, the Northern Rocky Mountains, and, more recently, the mountains of the US American West.
Michael J. White, Brown University
Michael White is a Professor of Sociology at Brown University. His areas of interest span demography and urban sociology with a particular interest in topics pertinent to public policy, such as US immigration policy, and the implications of migration for health in developing countries. Much of his research is unified by a concern for population distribution and migration: processes of movement, settlement, and adjustment. This interest is applied to a wide variety of geographic settings, looking at urbanization in China and Vietnam; urban growth, health and environmental change in Africa; and international migration to high income countries.
