Greg Castillo is Associate Professor of Architecture at the School of Environmental Design at the University of California, Berkeley. Professor Castillo, who is also a Research Associate at the United States Studies Centre at the University of Sydney in Australia, specializes in the architectural history of Interwar and Postwar America and Europe. His research explores the design legacies of the Cold War, focusing primarily on divided Germany as a case study site. He has received research fellowships from the German-American Fulbright Commission, the Getty Research Institute, the Kennan Institute for Advanced Russian Studies, the Canadian Centre for Architecture, and the Ford Foundation. He is author of Cold War on the Home Front: The Soft Power of Midcentury Design as well as numerous articles focusing on interwar and postwar America and Europe. Castillo's most recent research extends to counterculture design: he is guest curator of the 2017 exhibition Hippie Modernism: The Struggle for Utopia at the Berkeley Art Museum and Pacific Film Archive, and the author of multiple essays on the topic. Professor Castillo holds a Master of Architecture and Ph.D. in architectural history from Berkeley.
