Dr. Ziehl oversees an active research program in the areas of structural prognostics, remote online monitoring and assessment, nondestructive evaluation, in-situ load testing, repair and strengthening, composite materials, and prestressed/reinforced concrete structures. His team works in many areas including modeling and assessment of structural degradation mechanisms such as corrosion, alkali-silica reaction, and fatigue. His work is related to diverse systems including nuclear structures, buildings, bridges, and aircraft. Research sponsors include the National Science Foundation, the U.S. Department of Energy, the National Institute of Standards and Technology, the National Science Foundation, South Carolina DOT and other state departments of transportation, and industry.
