Prof. Shah has been actively involved in concrete technology research for several decades. His research addresses a variety of topics in concrete materials science and engineering, including high-strength concrete, shrinkage measurement, nondestructive test methods to monitor properties ranging from setting time to the modulus of elasticity, and rheology of fresh concrete, self-consolidating concrete, and nanotechnology applications. He has made pioneering and groundbreaking contributions to understanding fiber-reinforced concrete, damage, and fracture and developing innovative experimental techniques. He served as a Professor of Civil Engineering, at Northwestern University and founded NSF-funded Center for Advanced Cement Based Materials (ACBM) including the academic partner universities of Illinois, Michigan, Purdue, and NIST. Currently, he is the Director of the Center of Advanced Construction Materials, Civil engineering department at the University of Texas at Arlington.
