Nathaniel Robert Walker is Associate Professor of Architectural History at The Catholic University of America. He earned his PhD at Brown University, and studies the relationships between architecture, aesthetics, public space, urban design, political power, and dreams of the future, both utopian and apocalyptic. He has published essays in ARRIS, Buildings and Landscapes, the Journal of the Society of Architectural Historians, Traditional Dwellings and Settlements Review, Utopian Studies, and a number of edited volumes, including Suffragette City: Women, Politics and the Built Environment, which he co-edited with E. Darling. He has curated two exhibitions dealing with the connections between architecture, urbanism, and human dreams: Building Expectations: Past and Present Visions of the Architectural Future (Bell Gallery, Providence), and The City Luminous: Architectures of Hope in an Age of Fear (City Gallery, Charleston, co-curated with J. Streit).
