Before joining Future Earth as the Director of the U.S. Global Hub at the University of Colorado, 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, where his work focused on major global change issues, including the impacts of climate change on biodiversity, the potential of landscape connectivity to mitigate the impacts of climate change, and the impacts of species loss on ecosystem function. Today, he serves as the Interim International Director of Future Earth and is overseeing a current transition to Future Earth's overall structure.
In addition to his decade+ of academic work, which has been published in top journals, Josh also served as the founding director of the Luc Hoffmann Institute, a global research center based in Switzerland focused on the co-creation of multi-disciplinary research. As director, Josh launched over a dozen research projects, including work on the Food-Energy-Water nexus in South-East 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.
