Prof. Ling Jin’s Collaborative Team Received Best Paper Award by The Innovation

We are thrilled to announce that Prof. Ling Jin, Assistant Professor of CEE, and his collaborative team have been awarded the Best Paper Award 2024-2025 by The Innovation, a leading interdisciplinary journal under Cell Press dedicated to promoting scientific application through cutting-edge research and high-quality reviews. This recognition marks a significant milestone for Dr Changchao Li, the first author and a postdoctoral fellow (Awardee of RGC Junior Research Fellow Scheme) supervised by Prof. Jin, as this is the second consecutive year that the paper titled “Ecology and Risks of the Global Plastisphere as a Newly Expanding Microbial Habitat” is honored by The Innovation. Last year, their work was recognized as Most Popular (2020–2024). The rise of plastic waste has led to the emergence of a new habitat for microorganisms known as the plastisphere. The study analyzes plastisphere samples from various ecosystems, revealing unique, diverse microbial communities. These communities can break down organic compounds and disrupt the nitrogen cycle, increasing harmful substances and pathogens. The study warns that if plastic emissions continue to rise, the expanding plastisphere could pose serious global health risks. We extend our heartfelt congratulations to Prof. Jin, Dr Li and all team members. This award highlights their continued commitment to groundbreaking research and scientific excellence.

PolyU Summer Institute 2025

The PolyU Summer Institute 2025 was successfully held on 21-25 July 2025. CEE welcomed 48 high school students across 9 countries to engage in a series of fun-filled activities including hands-on workshop and company visit. Hosted by Prof. Andy Y.F. Leung, Associate Head of CEE, students were introduced to the academic programmes offered by the Department and gained insights into the field of civil engineering. One of the highlights was the Tower Challenge: Engineering with Straws, Tape, and Imagination, where the students were tasked with building the tallest possible tower using only a limited number of straws and tape. The challenge required both creativity and engineering skills to construct a tall yet stable free-standing tower. Remarkably, one of the winning teams achieved an impressive height of 111cm, breaking CEE’s previous record of 92 cm. Some of the students also had the opportunity to join the company visit to ARUP, a renowned consulting firm in civil engineering. During the visit, they learned about the industry developments, upcoming construction projects and career prospects in Hong Kong through interactive games and alumni sharing session. Ir Dr Goman Ho, Arup Fellow and President of the PolyU Civil and Environmental Engineering Alumni Association (CEEAA), hosted the visit and shared his expertise with the students. We hope all participants enjoyed the programmes and discovered their interests while gaining valuable experience in PolyU CEE.  

CEE PhD Students Won Student Benchmark Competition at CICE 2025

Congratulations to Mr Zeyu Gao, Ms Yifei Wang and Ms Yanran Meng, CEE PhD students supervised by Prof. Tao Yu, for winning first place in the Student Benchmark Competition (Analytical Model Category) at the 12th International Conference on Fiber-Reinforced Polymer (FRP) Composites in Civil Engineering (CICE 2025). The conference was held in Lisbon, Portugal, from 14 - 16 July 2025, as a joint national initiative organized by the University of Lisbon, the National Laboratory for Civil Engineering, and the University of Minho. Students from around the globe participated in the Student Benchmark Competition, where they were being challenged to predict the behavior of reinforced concrete beams strengthened with NSM-CFRP laminates under serviceability and ultimate limit states. This year, submissions came from universities worldwide, and after a rigorous selection process, the best predictions were awarded in each category (analytical models and finite element models). Once again, congratulations to our talented PhD students on this remarkable achievement!
