Biography
Ladd Keith, Ph.D., is an associate professor in the School of Landscape Architecture and Planning and a faculty research associate at the Udall Center for Studies in Public Policy at the University of Arizona. His transdisciplinary research focuses on heat planning, policy, and governance to help increase the heat resilience of communities, regions, and nations across the world. He is the UA lead of the Southwest Urban Corridor Integrated Field Laboratory (SW-IFL) funded by the U.S. Department of Energy, the co-lead of the Center for Heat Resilient Communities funded by the U.S. National Integrated Heat Health Information System (NIHHIS), the heat research lead of the Climate Assessment for the Southwest (CLIMAS) funded by the U.S. National Oceanic and Atmospheric Administration, co-investigator of the Building Resilience Against Climate Effects (BRACE) funded by the U.S. Centers for Disease Control and Prevention, and co-investigator of the Southwest Center on Resilience for Climate Change and Health (SCORCH) funded by the U.S. National Institutes of Health. He also serves on the Management Committee for the Global Heat Health Information Network (GHHIN), a World Health Organization and World Meteorological Organization joint initiative to protect global populations from the health risks of extreme heat. He has a Ph.D. in Arid Lands Resource Sciences and an M.S. in Planning from the University of Arizona.
