Tobias Baskin joined the board in 2007.  He is a Professor in the Biology Department at the University of Massachusetts Amherst where he leads a laboratory investigating the regulation of plant morphogenesis during growth and development. Dr. Baskin is recognized for his research into how plants control their shape via cellulose microfibrils and the microtubule cytoskeleton. He has made fundamental contributions to our understanding of how local cortical microtubule organization is related to microfibril orientation, which constrains cell and, ultimately, organ growth in longitudinal and radial directions. He has combined physiological, cytological, ultrastructural and genetic approaches to his studies of cell growth, and is credited with important innovations of microscopic techniques. Dr. Baskin is currently investigating the interaction of specific proteins with cortical microtubules, the plasmamembrane, and the cellulose synthase complexes in the membrane, to critically evaluate his proposed model of cell wall control of its own microfibril orientation.

Jon D. Erickson joined the board in 2004. He is Professor of Ecological Economics at the University of Vermont’s Rubenstein School of Environment and Natural Resources and Fellow of the Gund Institute for Ecological Economics.  He teaches both undergraduate and graduate courses in ecological economics (EE); leads an international service-learning program in the Dominican Republic focused on human rights and health in migrant communities; and leads a research program on both the theoretical development of EE and applied work on human and ecosystem health, rural livelihoods, regional sustainable development, land and biodiversity conservation, watershed planning, forest management, climate change policy, and renewable energy technology.  He has published extensively on these topics, including a co-edited book on The Great Conservation Experiment: Voices from the Adirondack Park.  Dr. Erickson is past president of the U.S. Society for Ecological Economics and former editor of the Adirondack Journal of Environmental Studies.

Patricia Fobare Erickson joined the board in 2005.  She is a practicing veterinarian and Senior Lecturer in the Animal Science Department at the University of Vermont where she teaches courses in Companion Animal Medicine, and Zoos, Exotics and Endangered Species.  She also leads service-learning courses to the Dominican Republic where she’s been working since 2005 in Haitian migrant settlements on community health interventions and HIV/AIDS prevention education.  Another dimension of her work is conservation medicine, an area she first got involved with as a participant in Jane Goodall’s Chimpanzoo Project, and more recently as an annual faculty member of Envirovet Institute.  Dr. Erickson received her Doctor of Veterinary Medicine at Cornell University, and when not teaching during the summer practices medicine in her hometown of Saranac Lake, NY.

He is Director of the Harvard Forest in Petersham, Massachusetts, and a professor in the Department of Organismic and Evolutionary Biology at Harvard University. A graduate of Connecticut College in botany and religion, he received his doctorate in ecology in 1983 from the University of Minnesota. His research focuses on the role of human land use, natural disturbance and environmental change in controlling the long-term development of boreal, temperate and tropical forest ecosystems in Scandinavia, Northeastern North America and the Yucatan.

Richard H. Goodwin, Jr. joined the board in 1984 and served as its treasurer from 1986 to 2002. He is president of Neuro Probe, Inc., a company which develops and manufactures biomedical research instruments. He is a graduate of Reed College and has pursued graduate studies in philosophy at the University of Pittsburgh. After two years on the faculty of the University of Maryland, he left teaching to establish his own enterprise. He now serves on the board of the Institute for Conservation Leadership.

Crea Lintilhac joined the board in 1994 and was secretary of the Foundation from 2001 through 2008. She is a graduate of Skidmore College and holds a masters degree in geology from the University of Vermont. She is involved with Lake Champlain research studies at the University of Vermont and Middlebury College, and also with conservation projects and education programs in Vermont. She is a director of the Lintilhac Foundation.

Philip M. Lintilhac joined the board in 2002. He is Associate  Research Professor in the Department of Plant Biology at the University of Vermont. Born in Shanghai in 1940, he spent most of the first ten years of his life in China. Graduating from the University of Vermont with a major in botany, he obtained his doctorate in the same field at the University of California, Berkeley, in 1971. After over four years conducting research as a post-doctoral fellow at Berkeley and at Stanford University, he returned to Vermont to join the faculty at the University. His research interests lie in the fields of plant development and physiology, in the pursuit of which he has invented a number of sophisticated biomechanical instruments. In 2006, Phil was honored by the Botanical Society of America with their Centennial Award.

V. Ernesto Mendez joined the board in 2010. He is an Assistant Professor with the Environmental Program and the Department of Plant and Soil Science, at the University of Vermont. His work analyzes interactions between agriculture, livelihoods, and biodiversity conservation in tropical and temperate landscapes, with an emphasis on small-scale farmers and their organizations. He is also a research associate with the Center for Tropical Ecology and Conservation at Antioch University New England, Adjunct Professor at the International University of Andalucia in Spain, and a founding member of Advising & Interdisciplinary Research for Local Development and Conservation in El Salvador,and the Community Agroecology Network in California. He holds degrees in Crop Science (California Polytechnic State University), Tropical Agroforestry (Tropical Agriculture Research and Education Center, Costa Rica), and a Ph.D. in Environmental Studies from the University of California, Santa Cruz.

William Ryerson joined the board in 2013. He is the Population Institute’s Chairman of the Board and Chief Executive Officer. Ryerson, who also serves as President of the Population Media Center, has a long history of working in the field of reproductive health, including 20 years of experience adapting the Sabido methodology for behavior change communications to various cultural settings worldwide. He has also been involved in the design of research to measure the effects of such projects in a number of countries, one of which has led to a series of publications regarding a serialized radio drama in Tanzania and its effects on HIV/AIDS avoidance and family planning use. Bill received a B.A. in Biology from Amherst College and an M.Phil. in Biology from Yale University (with specialization in Ecology and Evolution). In 2006, he was awarded the Nafis Sadik Prize for Courage from the Rotarian Action Group on Population and Development.
