Architect, urbanist and scholar, Rafi Segal received his PhD from Princeton University, and his M.Sc and B.Arch from Technion – Israel Institute of Technology. His practice encompasses design and research on both the architectural and urban scale. Segal’s projects include Villa 003 of the ORDOS 100 Project, the Kitgum Peace Museum in Uganda, the Ashdod Museum of Art and recently the winning proposal for the National Library of Israel in Jerusalem. His architectural work explores the relation of building to ground and contemporary notions of collective space. Segal’s writings and exhibitions, among them Cities of Dispersal (2008), Territories — Islands, Camps and Other States of Utopia (2003), and A Civilian Occupation (2003) have been extremely influential in the social- political discourse of contemporary urbanism. He has taught architecture and urban design at Harvard, Princeton, MIT, The Cooper Union School of Architecture and currently teaches at Columbia University’s Graduate School of Architecture.
