Benjamin Ibarra-Sevilla is an Associate Professor of Architecture and Historic Preservation, Program Director Masters Advanced Studies, and Program Coordinator Masters of Science in Historic Preservation. He is an architect who graduated from the National Autonomous University of Mexico (UNAM) and holds a degree in Conservation and Restoration of Built Heritage from the Excellence Program of the Carolina Foundation and the University of Alcalá de Henares, Spain. Previous to UT Austin, Prof. Ibarra-Sevilla was part of the faculty at the University of Minnesota's School of Architecture where he taught design and building technology courses and was a Research Fellow of the Center for World Heritage Studies.
His expertise involves case studies of ancient mason techniques, stereotomy, descriptive geometry, and architectural geometry informed by form-resistant structures. His most recent research work focuses on the transmission of building technology from Europe to the Americas exploring the constructive and geometric analysis of sixteenth-century ribbed vaults in Mexico. His work in masonry, geometry, and stereotomy has been awarded in Mexico and the US and has been disseminated in various forums and journals of Europe, Latin America, and North America. His most recent book named "Mixtec Stonecutting Artistry" published by the National Autonomous University of Mexico has received numerous awards, and his exhibition holding the same name has been traveling for two years through eight cities of Mexico and the United States. Benjamin has participated in developing assistance for world heritage cities such as Zanzibar in Tanzania, Baku in Azerbaijan, and the Batanes Islands in the Philippines. He recently participated with Ochsendorf DeJong & Block in the project "Beyond Bending" designing and constructing tile vaults exhibited at the Architecture Biennale in Venice 2016.

As an educator and designer, Benjamin's Design Studios focus on the current challenges of historic preservation, including adaptive reuse and insertions of contemporary pieces of architecture in historic urban landscapes. His seminar "Secret Knowledge, Rediscovering the Methods and Techniques of the Old Master Builders" explores the relationships between geometry, space, and structure while learning the challenges faced by gothic and renaissance designers. Prof. Ibarra-Sevilla has a profound interest in building technology; he teaches Construction 1which is the introductory course of the technology sequence within the graduate program. His Graphic Documentationcourse focuses on developing documentation projects of historic buildings following the HABS guidelines, and in recent years the work developed in this class has been under contract with the National Park Service. Within these documentation efforts, Prof. Ibarra-Sevilla works with students exploring traditional methods of documentation and digital technologies such as Laser Scanner and Digital Photogrammetry as vehicles for assessment and visualization of historic properties.
Before his career as an academic, Prof. Ibarra-Sevilla worked in restoration projects in Oaxaca, Mexico including the seventeenth-century Ex-Convento of Santo Domingo de Guzman, the sixteenth-century Open Chapel of San Pedro y San Pablo Teposcolula, the sixteenth-century Casa de la Cacica (also in Teposcolula) and the eighteenth-century Casa de la Ciudad Oaxaca City. Associate Professor Ibarra-Sevilla has a passion for photography, he believes in this media and its potential as a design tool, a documentation tool, and as an art that captures space and time in one frame.
Professor Ibarra is the first Mexican to obtain tenure at UT School of Architecture.
