Elizabeth A. Hadly is the Paul S. & Billie Achilles Professor of Environmental Biology and Faculty Director of Jasper Ridge Biological Preserve at Stanford University where she has been on the faculty since 1998. Hadly is a global change scientist who has spent more than 30 years studying the impacts of environmental change of the past, present, and future on biodiversity. Her research has taken her from Yellowstone National Park to the top of Mount Kilimanjaro, from the Himalayas to the jungles of Rwanda, from the grassland steppe of Patagonia to the Kalahari Desert, and from the Arctic to the Antarctic in her ongoing efforts to understand and communicate about how people are changing the planet. Hadly seeks to reach outside the ivory tower on issues related to climate change, disease, pollution, extinction, habitat loss, and human population growth—all features of our human-dominated epoch, The Anthropocene.
