About
Dr. Madhu M. Karthik is a leading expert in nondestructive evaluation (NDE) and structural health monitoring, with a particular focus on critical infrastructure such as underwater tunnels and bridges. Her most cited work, "Nondestructive Testing Methods for Underwater Tunnel Linings: Practical Application at Chesapeake Channel Tunnel" (2016, 15 citations), represents a landmark field study that systematically evaluated a suite of NDT techniques—including visual inspection, ground-penetrating radar (GPR), ultrasonic tomography (UST), and impact echo (IE)—on an active underwater tunnel. Notably, she pioneered the use of air-coupled GPR antennas in this challenging environment, demonstrating how to detect hidden defects without direct contact. This practical, multi-method approach has become a benchmark for infrastructure assessment, directly influencing inspection protocols for aging tunnels worldwide. Dr. Karthik’s work bridges the gap between laboratory research and real-world application, providing engineers with validated tools to ensure safety and extend service life. Her contributions are essential reading for students and researchers in civil engineering, geophysics, and asset management, offering a clear roadmap for implementing advanced NDT in demanding underwater settings.
