We are a Hong Kong-based research group dedicated to both the fundamental research of Ultrasonics and ultrasonics-enabled engineering and bio-engineering applications such as Structural Health Monitoring (SHM) and Acoustofluidics. Our key research interests lie primarily in a broad area including ultrasonics, wave propagation, guided-wave-based SHM, sensor and sensor network, non-destructive evaluation, smart materials and structures, and advanced composites.
We are very happy to welcome four new PhD candidates and one postdoctoral fellow to join the Group: Miss. Xin GONG from Beihang University, Mr. Jianbin LI from Tongji University, Mr. Jiaxing TIAN from Harbin Institute of Technology, and Mr. Shuchang ZHANG from Huazhong University of Science and Technology, as well as Dr. Zaiwei LIU from Tianjing University.

Congratulations to Yi HE and Tianhui LU, for having successfully defended their theses and received PhD degrees! Well done, Dr. HE and Dr. LU!
We are thrilled to present the latest development of a free software to calculate the dispersive properties of physical guided waves in acoustoelastic and complex waveguides. Developed based on a semi-analytical finite element method, we name this freeware SAFEDC. This freeware can now be downloaded via the following link https://sourceforge.net/projects/safedc/.
We are organizing SPIE Conference on Health Monitoring of Structural and Biological Systems 2025. The call for papers is now online (https://spie.org/SS25/conferencedetails/health-monitoring-structural-biological-systems#_=_). We look forward to meeting you in Vancouver, Canada, 17-20 March 2025.
Congratulations to Zhou Pengyu, Xu Lei, Su Yiyin, Yang Xiongbin, Yang Jianwei and Fan Haiyan, for having successfully defended their theses in 2022-2023 and received PhD degrees! Well done, Dr. Zhou! Dr. Xu! Dr. Su! Dr. YANG!, one more Dr. YANG! and Dr. Fan!
The SU Research Group is dedicated to both the fundamental and applied research in the field of ultrasonics, structural health monitoring (SHM), non-destructive evaluation (NDE), elastic wave propagation, smart materials and structures, sensor and sensor network, and advanced composite materials. It enjoys burgeoning growth since its establishment in 2007, consistently outputting high-quality publications in top-tier journals and securing research grants from various sources. In the pursuit for excellence, the Group is proactively applying research achievements to real-world engineering applications, and recent paradigms include the SHM technique/system developed for high-speed trains, space assets, and aircraft structures. The Group is well-equipped with state-of-the-art facilities, enabling innovative research and development of cutting-edge technologies. With recognition from peers and colleagues, the Group has networked with dozens of research groups at the frontier of today’s SHM technology, with solid partnership from Australia, China, Poland, Republic of Korea, the USA, the UK and many others.

Bio-sketch
Prof. Zhongqing Su is the Chair Professor of Intelligent Structures and Systems and Head of the Department of Mechanical Engineering at The Hong Kong Polytechnic University (PolyU). He is the current Editor-in-Chief of the journal Ultrasonics (Elsevier), and he holds the Changjiang Chair Professorship. He is an elected Distinguished Fellow of the International Institute of Acoustics and Vibration (IIAV). Since 2023, Prof. Su has been the Vice President of The Hong Kong Society of Theoretical and Applied Mechanics (HKSTAM). His research interests span the area of ultrasonics, structural health monitoring (SHM), wave propagation, sensors and sensor network, nondestructive evaluation, smart materials, and advanced composites.
Prof. Su earned his PhD in 2004 from the School of Aerospace, Mechanical and Mechatronic Engineering at The University of Sydney, where he also completed his postdoctoral training in 2005–2006 under the support of the competitive “Australian Research Council – Australian Postdoctoral Fellowship” (ARC-APF). He joined PolyU in 2007 as an Assistant Professor and was promoted through the ranks to Chair Professor. He has been the Head of Department since 2021. Apart from his key editorial commitment as the Editor-in-Chief of Ultrasonics, Prof. Su has served as the Associate Editor of nine key international journals in the field, including Journal of Sound and Vibration, Structural Health Monitoring: An International Journal, Structural Engineering and Mechanics, and ASME Journal of NDE. He has been a Panel Member of the Hong Kong Innovation and Technology Fund (ITF) since 2021.
Prof. Su was/is the Chair of a number of top international conferences in his field, including the 7th Asia-Pacific Workshop on SHM (APWSHM 2018, Hong Kong, 2018), the SPIE Conference on Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2023 (Long Beach, the United States, 2023), and the SPIE Conference on Health Monitoring of Structural and Biological Systems XVIII (Long Beach, the United States, 2024). He was also the Co-Chair of the SPIE Conference on Health Monitoring of Structural and Biological Systems from 2019 to 2023, and the SPIE Conference on Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems in 2021 and 2022. Prof. Su received the “SHM - Person of the Year Award” in 2012, the “Dragon-Star Innovation Award (1st Place)” from the European Commission in 2015, and twice the “Natural Science Award for Higher Education Outstanding Scientific Research Output” from the Ministry of Education, China. At PolyU, he is a recipient of the “President’s Award for Excellent Performance/Achievement in Research and Scholarly Activities”, the “Faculty Award for Outstanding Performance in Research”, and thrice the “Faculty of Engineering Research Grant Achievement Award”.
We treasure the contribution from every single group member.

Ultrasonics is the only internationally established journal which covers the entire spectrum of ultrasound research, technology and applications. Ultrasonics contains a variety of sections to keep its readers abreast of the state of the art in both fundamental investigation and real-world development related to ultrasonics. Ultrasonics publishes papers of exceptional quality and of relevance to both academia and industry. Manuscripts in which ultrasonics is the core and not simply an incidental tool or secondary issue are welcomed.
Structural Health Monitoring: An International Journal is an international peer reviewed journal that publishes the highest quality original research that contain theoretical, analytical, and experimental investigations that advance the body of knowledge and its application in the discipline of structural health monitoring. The journal has a broad topical coverage and it serves as a primary reference for the structural health monitoring of aeronautical, mechanical, civil, electrical, and other systems. The multidisciplinary nature of the journal is intended to foster the intersection of different technologies to address the varied needs and applications for structural health monitoring.
