Dr. Khosrow Bozorgi, professor of Architecture at the Christopher C. Gibbs College of Architecture at the University of Oklahoma, is advancing a major research project that examines how societies across time and place have organized the built environment in strikingly similar ways.
Dr. Bozorgi’s work draws on fieldwork conducted across five cultural contexts—ancient Roman Tunisia, medieval Morocco, Safavid Iran, Hanseatic Germany, and pre-Columbian New Mexico. Across these cases, he has found that settlements consistently organize space in three parts: an outward-facing public realm, a semi-private transitional zone, and a protected interior domain.
His project frames this pattern as a form of convergent architectural evolution. Independent cultures, working without shared contact or precedent, have arrived at comparable spatial solutions to address common human concerns, including climate, social interaction, and privacy.

Dr. Bozorgi’s research integrates original measured drawings, site documentation, and longitudinal analysis across these regions, and comparative analysis is central to Dr. Bozorgi’s project. At Pueblo Bonito in Chaco Canyon, ancestral Puebloan builders used massing and orientation to manage extreme desert conditions. At the Ganjali Khan Complex in Kerman, Iran, a dense network of passages and wind towers facilitates air movement and cooling. While the technologies and environmental strategies differ, both environments reflect the same underlying spatial sequence from public to private space
Dr. Bozorgi’s findings will be presented in his forthcoming book, The Grammar of Space: Architectural Patterns Across Time and Culture, which is currently under contract with Birkhäuser, with publication expected in 2027.
On April 24, 2026, the Christopher C. Gibbs College of Architecture hosted its annual Graduate Student Showcase, a celebration of research, design innovation, and creative exploration across all graduate programs within the College.
The Gibbs College of Architecture celebrates fifth-year architecture student Haley Praytor, who has been recognized at the national level for her design work. In early March, Haley received a Graduate Division Award of Merit for her submission to the 2025 Metal Building Manufacturers Association student design competition.
Ronald Frantz Jr., emeritus professor, has been named a 2026 Mary Means Leadership Award recipient, the highest honor presented by Main Street America. The award was announced at the Main Street Now Conference in Tulsa, recognizing leaders who advance preservation-based economic development and community revitalization.
