Ronald Rael is Associate Professor in the departments of Architecture and Art Practice at the University of California. In 2014, his creative practice was named an Emerging Voice by the Architectural League of New York. On this edition of Conversations, he joins me to talk about his book, Borderwall as Architecture: A Manifesto for the U.S.-Mexico Boundary. The book presents a history of the wall and examines how its presence disrupts people and the environment. As a way of encouraging dialog about the borderwall, Rael presents wall designs that range from the whimsical to the practical. He also shares stories of activities along the wall including horse races, volleyball and yoga classes.
