Pour-Ghaz studies the durability of reinforced concrete materials and structures with the goal of better understanding the deterioration mechanisms and distress factors affecting the concrete infrastructure. His studies aim at developing mechanistic models for accurate service life prediction of concrete infrastructure and developing test methods for fundamental material characterization. Pour-Ghaz also performs research in the area of Nondestructive Testing (NDT) and Structural Health Monitoring (SHM). Specifically, he investigates the use of electrical, ultrasonic, acoustic, and hybrid imaging for monitoring damage development and moisture ingress in concrete.
