Research Interests and Background
Brad Udall has an extensive background in water and climate policy issues, including as Director of the Western Water Assessment (University of Colorado), as the first Director of the Getches-Wilkinson Center for Natural Resources, Energy and the Environment (University of Colorado), and currently as the first senior water and climate research scientist/scholar at the Colorado Water Institute (Colorado State University). He has written extensively on the impacts of climate change on water resources in the American West. He was the lead author of the water sector chapter of the Global Climate Change Impacts in the United States (2009), a publication of the United States Global Change Research Program, and was an author of the Western Water Assessment’s Climate Change in Colorado Report. He was formerly a consulting engineer and the managing partner at Hydrosphere Resource Consultants. The California Department of Water Resources awarded him its Climate Science Service Award for his work in facilitating interactions between water managers and scientists, and the Department of Interior bestowed the Partner in Conservation Award on the Western Water Assessment for his work on the groundbreaking 2007 EIS on Colorado River shortages and coordinated reservoir operations. He has an engineering degree from Stanford and an MBA from Colorado State University.
