Ecologist, author, and cancer survivor, Sandra Steingraber, Ph.D. is an internationally recognized authority on the environment links to cancer and human health. Steingraber’s highly acclaimed book, Living Downstream: An Ecologist’s Personal Investigation of Cancer and the Environment presents cancer as a human rights issue. Originally published in 1997, it was the first to bring together data on toxic releases with data from U.S. cancer registries. Continuing the investigation begun in Living Downstream, Steingraber’s book, Having Faith: An Ecologist’s Journey to Motherhood, explores the intimate ecology of motherhood and the extent to which environmental hazards threaten each stage of infant development. An enthusiastic and sought-after public speaker, Steingraber has keynoted conferences on human health and the environment throughout the United States and Canada and has been invited to lecture at many universities, medical schools, and hospitals. She is recognized for her ability to serve as a two-way translator between scientists and activists.
