Dr. Xiaoyu Yang obtained his BSc degree in Electromechanical Engineering from Zhejiang University in 2016, then immediately pursued his Ph.D. in the same field at Zhejiang University. His Ph.D. project was centered around the ultrasonic assessment of composite materials. In 2019, Xiaoyu started a joint Ph.D. degree program between Zhejiang University and Ghent University. In September of that year, he relocated to Ghent, Belgium, to begin his research on the ultrasonic assessment of fiber-reinforced polymers with the Mechanics of Materials and Structures research group at Ghent University. Upon completing his Ph.D., Xiaoyu started a postdoctoral research position at Ghent University, where he continued his studies in Nondestructive Testing and Evaluation (NDT&E) and composite material testing. In April 2023, he took on a new role as a research fellow in the Ultrasonics and NDE Group at NTU. His research interests include NDT/E, signal processing, composite material characterization, and (laser) ultrasonics.
