Josh Tewksbury was trained as an ecologist, evolutionary biologist, and conservation biologist. He has 20+ years of active research focused on climate impacts on plants and animals; the influence of fragmentation, connectivity, invasive species and mutualism loss on populations and communities; the evolution and functional significance of chemical defense in plants; and other topics.
Before joining Future Earth as the Director of the Colorado Global Hub, Josh was the founding director of the Luc Hoffmann Institute, a global research center integrated within the International Secretariat of the World Wide Fund for Nature in Geneva Switzerland. While there, Josh started the Luc Hoffmann Fellows programme and launched over a dozen research projects, including work on the Food-Energy-Water nexus in Southeast Asia, Development corridors in East Africa, global mapping of threats to biodiversity and the development of regionally-appropriate low-carbon sustainability targets for urban areas.
Prior to his work at the Luc Hoffmann Institute, Josh was the Maggie and Doug Walker Endowed Professor of Natural History at the University of Washington, with appointments both in the Department of Biology and the College of the Environment, which he worked to create.
