Dr. Lingyu Yu’s research interests include structural health monitoring (SHM) and nondestructive evaluation (NDE) using ultrasonic guided waves supported by active sensor technology, theoretical modeling, advanced signal processing and data analysis; damage diagnosis in complicated structures; scanning laser vibrometry for guided wave propagation; and mechatronics. Current research efforts include developing a multi-scale damage detection approach on composite structures, developing imaging strategies for permanently installed SHM system to perform in-situ damage detection, and exploiting advances made in other areas to introduce innovative methods into SHM/NDE.
