PolyU scholar Prof. Yi-Qing NI receives 16th Guanghua Engineering Science and Technology Award by the Chinese Academy of Engineering
Professor Yi-Qing NI, Yim, Mak, Kwok & Chung Professor in Smart Structures, Chair Professor of Smart Structures and Rail Transit of the Department of Civil and Environmental Engineering, Director of the PolyU-Hangzhou Technology and Innovation Research Institute, and Director of National Rail Transit Electrification and Automation Engineering Technology Research Centre (Hong Kong Branch) at The Hong Kong Polytechnic University (PolyU), has been honoured with the 16th Guanghua Engineering Science and Technology Award by the Chinese Academy of Engineering.
The Guanghua Engineering Science and Technology Award is a national award presented biennially and is hailed as “the highest award in China’s engineering sector”. It aims to honour Chinese engineers and scientists who have made outstanding achievements and significant contributions in engineering science and technology, and engineering management. Since its establishment in 1996, the Award has recognised 423 distinguished individuals from different engineering fields. This year,40 awardees were selected from 471 candidates, including one Guanghua Engineering Science and Technology Achievement Award recipient and 39 Guanghua Engineering Science and Technology Award recipients, with Prof. Ni one of the three Award recipients from Hong Kong.
Prof. Ni is world-renowned scholar in the fields of structural health monitoring and vibration control. He was ranked in the World’s Top 2% Most-Cited Scientists in rankings released by Stanford University for six consecutive years from 2020 to 2025 (in both the career-long and single year citation categories). He was also ranked among the world’s top 0.05% scholars on the 2025 ScholarGPS Highly Ranked Scholars – Lifetime list and placed fourth globally in the field of “Structural Health Monitoring”.
Prof. Ni was nominated by PolyU President and Academician of the Chinese Academy of Sciences, Prof. Jin-Guang TENG. Prof. Teng congratulated him saying, “This award carries profound significance. It not only affirms Prof. Ni’s dedication and outstanding achievements over the years, but will also inspire PolyU staff and students to continue upholding the spirit of innovation in service of the long-term development of the nation and society.”
Prof. Ni expressed his gratitude, “I am deeply grateful to the President for his trust and nomination, and I would also like to thank the research team that has worked alongside me over the years. We have always upheld a spirit of continuous innovation and change, starting from real-world needs to advancing smart rail transit and structural safety monitoring technologies, and applying our research outcomes to major infrastructure projects in Hong Kong and in the country more widely. Looking ahead, my team and I will continue to work hard to bring innovative PolyU technologies onto the international stage, deepen collaboration with the Chinese Mainland and overseas partners, enable more people to benefit and make greater contributions to national development and the long-term well-being of society.”
Prof. Ni joined PolyU in 2001. His research expertise covers structural health monitoring, structural dynamics and control, smart materials and structures, and sensor technologies. As a core member of PolyU’s multi-disciplinary rail technology research team, he has contributed to the development of fibre Bragg grating sensors that have significantly enhanced the safety and stability of railway services. These devices can be installed on railway tracks and connected to fibre-optic cables, helping maintenance staff more effectively monitor wheel flats and rail conditions, carry out repairs in a timely manner, and safeguard passenger safety.
In 2015, PolyU was approved by the Ministry of Science and Technology of the People’s Republic of China to establish the Hong Kong Branch of the National Rail Transit Electrification and Automation Engineering Technology Research Centre, with Prof. Ni serving as Director. The Centre brings together professors from five departments across two PolyU faculties to study high-speed rail from an integrated and macro perspective. Leveraging the internationalisation of China’s high-speed rail, the Centre exports its monitoring systems overseas, thereby promoting Hong Kong’s innovative technologies to the world.
Prof. Ni has an outstanding record of research achievements and has received numerous accolades. The monitoring systems he has helped develop have won multiple awards at the Geneva International Exhibition of Inventions in Switzerland and at the China International Industrial Fair. In 2016, the project “Key technologies for building the Canton Tower”, in which he participated, received a second-class State Scientific and Technological Progress Award.
Beyond his dedication to academic and scientific research, Prof. Ni is also committed to advancing knowledge transfer. As Director of the PolyU-Hangzhou Technology and Innovation Research Institute, he leads the Institute in focusing on areas such as intelligent transportation, Grand Canal culture and tourism, and medical aesthetics, actively aligning PolyU’s research strengths with local industrial development and societal needs to accelerate the real-world application of research outcomes for the benefit of society.
