Dr. Stephen Jackson is the Senior Advisor on Biodiversity and Climate Change for the Climate Adaptation Science Center network.

Stephen T. Jackson is Senior Advisor on Biodiversity and Climate Change. Prior to this role, he served as Director of the Southwest and South Central Climate Adaptation Science Centers, partnerships between the U.S. Geological Survey and multi-university consortia respectively led by the University of Arizona and the University of Oklahoma. In this position, he worked to foster effective engagement between researchers and resource-management decision-makers. He is also Adjunct Professor of Geosciences and of Natural Resources & Environment at the University of Arizona. Before joining USGS in 2012, he was at the University of Wyoming, where he was founding Director of the Program in Ecology and is now Professor Emeritus of Botany.

Jackson’s research has focused on using the past 25,000 years of earth history as a source of natural experiments to explore ecological responses to environmental changes of various kinds, rates, and magnitudes. His interests also include the history of science, and he has edited two English translations of classic works by Alexander von Humboldt, with a third nearing completion.
