Tyler S. Sprague PE., Ph.D. teaches courses in structural design & architectural history. He holds engineering degrees from the University of California, Berkeley and the University of Washington (UW) and worked professionally as a structural engineer before completing a Ph.D. in architectural history in the College of Built Environments at the UW.
Dr. Sprague's research investigates the intersection of architecture and structural engineering, both in Modern architecture and the present. His doctoral dissertation "Expressive Structure: The Life and Work of Matthew Nowicki" examines the designer of the first tension-hung roof in the United States (the Dorton Arena in Raleigh, NC, begun in 1950). He has also published on the rise of concrete skyscrapers in the Pacific Northwest, the structural engineers of the 1962 Seattle Worlds Fair, and the thin shell concrete structures designed by Jack Christiansen. Tyler has received funding from the Global Architectural History Teaching Collaborative (GAHTC) as well as the Precast Concrete Institute (PCI). He currently serves on the board of both the Construction History Society of America and the local chapter of docomomo (for Western Washington). He remains active with the Building Technology Educators Society (BTES), the Society of Architectural Historians, the National Center for Preservation Technology & Training.
