Carolyn Raffensperger, M.A., J.D., is executive director of the Science and Environmental Health Network (SEHN). An archaeologist as well as a lawyer, she worked for many years for the Sierra Club on issues including forest management, river protection, pesticide pollutants, and disposal of radioactive waste. She joined SEHN in 1994. Raffensperger is co-editor of Precautionary Tools for Reshaping Environmental Policy, published by MIT Press (2006) and Protecting Public Health and the Environment: Implementing the Precautionary Principle, published by Island Press (1999). She has served on editorial review boards for several environmental and sustainable agriculture journals, and on U.S. EPA and National Research Council committees. From 1999 until recently, she wrote a bimonthly column for the Environmental Law Institute’s Environmental Forum.

Ted Schettler, M.D., M.P.H.
, SEHN’s science director, received his M.D. from Case-Western Reserve University and a master’s degree in public health from the Harvard School of Public Health. He practiced medicine for many years in New England and has worked with community groups and non-governmental organizations throughout the U.S. and internationally, addressing many aspects of human health and the environment. He has served on advisory committees of the U.S. EPA and National Academy of Sciences and continues to work closely with Greater Boston Physicians for Social Responsibility. Schettler is co-author of Generations at Risk: Reproductive Health and the Environment, about the reproductive and developmental health effects of exposure to environmental toxicants; and of In Harm's Way: Toxic Threats to Child Development, about the impact of environmental exposure on neurological development in children. His current projects include heading the science work group for the Collaborative on Health and Environment (CHE) and active participation in the Health Care Without Harm coalition.

Joseph H. Guth, J.D., Ph.D.
, SEHN legal director, received his legal training at NYU and also holds a Ph.D. in biochemistry. Guth has worked on Clean Water Act citizen’s suits and toxic chemicals regulatory policy for the Natural Resources Defense Council, and on environmental torts, intellectual property, and products liability as a litigator in the private sector. He served as executive director of the California League for Environmental Enforcement Now, a coalition of environmental groups and law firms, and as senior policy analyst for the Center for Environmental Health, both in California. Guth is currently a member of Cal/EPA’s Cumulative Impacts and Precautionary Approaches Workgroup, working to implement California's Environmental Justice Action Plan. In addition to advocating the reform of chemicals policy in the U.S. and California, Guth works toward the transformation of law to promote the preservation of the Earth, rather than accept environmental destruction as a byproduct of economic growth; in this, he concentrates on property law, the public trust doctrine, law of the commons, ecological economics and the precautionary principle.
