Vice President

Juenger is the L.B. (Preach) Meaders Professor of Engineering in the Department of Civil, Architectural and Environmental Engineering at The University of Texas at Austin in Austin, Texas. Juenger’s teaching and research focus on materials used in civil engineering applications. She primarily examines chemical issues in cement-based materials, including phase formation in cement clinkering, hydration chemistry of cements and supplementary cementitious materials, and chemical deterioration processes in concrete. Her current research efforts emphasize the interaction of cement-based materials and the environment. This work encompasses the development and characterization of cementitious systems with lower carbon dioxide and energy footprints, as well as the capacity of cementitious materials to produce or remove airborne and waterborne pollutants.

Juenger is a Fellow of ACI and the American Ceramic Society. She is a member of numerous ACI committees and has received several awards from ACI for her research, teaching and service, including the 2009 Walter P. Moore, Jr. Faculty Achievement Award, 2010 ACI Young Member Award for Professional Achievement, 2011 Wason Medal for Materials Research, 2018 Delmar L. Bloem Distinguished Service Award and 2020 ACI Concrete Sustainability Award. She has also received a Faculty Early CAREER Award from the National Science Foundation. She is on the Editorial Boards of both Cement and Concrete Research and Cement and Concrete Composites.

Juenger received her Bachelor of Science degree in chemistry from Duke University in Durham, North Carolina, and her doctorate in materials science and engineering from Northwestern University in Evanston, Illinois. After completing her doctorate, she was a postdoctoral researcher in civil engineering at the University of California, Berkeley in Berkeley, California, before coming to The University of Texas at Austin.
