Zachary Tate Porter is a historian, educator, and designer based in Los Angeles. His research focuses primarily on the shifting conceptions of ground that undergird architectural production. He holds a PhD in Architectural History from the Georgia Institute of Technology, as well as a Master of Architecture and Bachelor of Arts and Architecture from the University of North Carolina at Charlotte. His dissertation project, “Shifting Grounds of Architectural Practice,” analyzes the ways in which jurisdictional competition shaped architecture, landscape design, and city planning during the early twentieth century. In 2015, Porter founded OOCA (Office of Contingent Affairs), a platform for architectural research and experimental historiography. Prior to joining USC, Porter was the 2015-16 Design of Theory Fellow at SCI-Arc, where he edited the online journal, Offramp.
