About the Author

Barzin Mobasher obtained his BS and MS in civil engineering from the University of Wisconsin-Platteville and Northeastern University in 1983 and 1985, respectively. He received his PhD in civil engineering from Northwestern University in 1990 and was a member of the Technical Staff at USG Corporation during 1990–1991. He joined the Department of Civil and Environmental Engineering at Arizona State University in 1991 as an assistant professor of structural materials. He has been a professor of engineering at ASU since 2004. Dr. Mobasher has led programs involved with the design, analysis, materials testing, and full-scale structural testing of construction and structural materials. His list of publications includes more than 150 research papers in leading professional journals and conference proceedings. He has made fundamental contributions to the field of fiber and textile reinforced concrete materials and mechanics of toughening in cement-based systems, modeling the mechanical and durability of materials, and experimental mechanics. He has served as the Chair of the American Concrete Institute, ACI Committee 544 on Fiber Reinforced Concrete, and has been a reviewer for a variety of journals.
