His ability to lead high-impact national projects, combined with his deep technical knowledge and innovation, underlines his suitability for leadership, advisory, or technical expert roles in critical infrastructure and research.
📘 Education & Experience
Dr. Jia Yu, a Ph.D. graduate in Hydraulic and Hydropower Engineering from Hohai University, has built a solid foundation in civil and structural engineering since earning his bachelor’s degree in Civil Engineering from Shandong Jianzhu University in 2013. He currently holds the position of Senior Engineer at the Nanjing Hydraulic Research Institute, a prominent national research institute under the Ministry of Water Resources, Ministry of Transport, and the National Energy Administration. With over a decade of academic and professional dedication, his work spans across infrastructure safety, diagnostic technologies, and hydraulic structures.
📈 Professional Development
Dr. Jia has served as principal investigator or core member on over 10 national and provincial research projects, including the National Natural Science Foundation Youth Program, the Jiangsu Natural Science Foundation, and key topics in the 14th Five-Year National Key R&D Plan. He contributed as the third drafting member for a national technical specification in water conservancy. His scholarly output includes 27 peer-reviewed publications (13 SCI-indexed), and he holds 32 granted invention patents, reflecting a sustained and multi-dimensional contribution to the field. His work has led to field-ready innovations, published in high-impact journals, and has influenced industry standards and safety practices.
🔬 Research Focus
Driven by the national priority of “safety first and prevention-oriented” in hydraulic infrastructure, Dr. Jia’s research targets early identification of micro-level damage—specifically cracks smaller than 0.05 mm, which traditional methods struggle to detect. His pioneering work explores selective excitation detection mechanisms, including ultrasonic thermography, numerical simulation, and the development of specialized test equipment. By integrating wide-band ultrasonic generators, infrared imaging, and modular excitation arrays, he advanced detection capability down to 0.01 mm-level microcracks, effectively redefining what’s possible in non-destructive testing (NDT) of concrete. These technologies significantly improve the predictive maintenance and disaster resilience of hydraulic infrastructure.
