Ladd Keith

Ladd Keith, Ph.D., is an assistant 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. An urban planner by training, he has over a decade of experience planning for climate change with diverse stakeholders in cities across the U.S. His research explores heat policy and governance to help communities increase their heat resilience. He is the UA lead of the Southwest Urban Corridor Integrated Field Laboratory (SW-IFL) funded by the Department of Energy, the heat research lead of the Climate Assessment for the Southwest (CLIMAS) funded by the National Oceanic and Atmospheric Administration, with additional research funding from the Centers for Disease Control and Prevention and the Department of Transportation. He also founded and led the Sustainable Built Environments undergraduate degree program which is offered in person, fully online, and globally in Peru and Ecuador. He has a Ph.D. in Arid Lands Resource Sciences and an M.S. in Planning from the University of Arizona.
