HKU Engineering research team led by Professor Tao Liu wins Best Paper Award at IET International Conference on APSCOM 2025
An engineering research team led by Professor Tao Liu, and Dr Zelin Liu (research postgraduate alumnus (2025), supervised by Professor Tao Liu), from the Department of Electrical and Electronic Engineering, has won the Best Paper Award for their best paper titled “Fast Modeling of Consecutive Load Redistribution Attacks for Large-Scale Power Systems” at The 13th IET International Conference on Advances in Power System Control, Operation and Management (APSCOM 2025), organised by The Institution of Engineering and Technology (IET).
In their work, the team developed a fast algorithm to address consecutive load redistribution attacks in power systems. Instead of repeatedly solving a mixed-integer linear program before each attack, their method solves the MILP only once and then efficiently derives subsequent attack vectors by parameterising and intersecting boundary constraints from the initial solution. Under typical operating assumptions, the approach guarantees global or local optimality while reducing computation time by orders of magnitude.

HKU Engineering student wins Best Poster Presentation Award at the 2025 TERMIS-AP Conference
Miss Xinyang Zhang, a final-year PhD student supervised by Professor Min Wang in the Department of Mechanical Engineering, has won the Best Poster Presentation Award (SYIS) at the Tissue Engineering and Regenerative Medicine International Society Asia-Pacific Conference 2025 (2025 TERMIS-AP) which was held on October 16-19, 2025 at the China Optics Valley Convention and Exhibition Center in Wuhan, China. TERMIS-AP conferences are among the most influential academic conferences in the field of tissue engineering and regenerative medicine in the Asia-Pacific region.
Miss Zhang’s presentation in this conference is entitled “Antioxidant-functionalized Hydrogel Scaffolds Fabricated by 3D Printing for Liver Tissue Regeneration”, which is based on her PhD work conducted at HKU. In this study, antioxidant hydrogel scaffolds were developed for liver tissue engineering by incorporating tannic acid (TA) into hierarchically structured, 3D printed chitosan-based scaffolds. The scaffolds were made using printable hydrogel inks consisting of chitosan methacrylate and xanthan gum, which were cross-linked and loaded with different amounts of TA. TA provided antioxidative, anti-inflammatory and antibacterial functions to the scaffolds. The printing inks exhibited good rheological properties and good printability, and 3D printed scaffolds displayed high fidelity and mechanical stability, as well as suitable water absorption and biodegradation behavior. In vitro experiments using fibroblasts and hepatocytes showed high cell viability, suggesting good biocompatibility of scaffolds. Moreover, antioxidant assays demonstrated that TA-loaded scaffolds effectively scavenged free radicals, with higher TA contents leading to stronger antioxidative performance, indicating their high potential for liver tissue regeneration applications.

HKU Engineering student team wins 1st Runner Up Award in IET Young Professionals Exhibition & Competition 2025
A postgraduate student team from the Department of Electrical and Electronic Engineering has been awarded the 1st Runner Up Award of the Institution of Engineering and Technology (IET) Young Professionals Exhibition & Competition (YPEC) 2025.
The HKU team—comprising Dr Zhenglong Li, Mr Songshi Dou, and Mr Tianqin Yang—was supervised by Dr Vincent W.L. Tam (Principal Lecturer of HKU EEE) and Professor Lawrence K. Yeung (Associate Dean (RPg) of Faculty of Engineering). Their award-winning project, titled “Developing A Coarse-to-Fine Grained Knowledge Refinement Framework for Network Intrusion Detection System”, impressed judges with its innovative approach to cybersecurity.
YPEC is an annual showcase and competition that brings together young engineers and students from diverse disciplines to present their innovations in engineering and technology. Organised by the IET and co-organised by EMSD (機電工程署), the event serves as a platform for emerging talent to demonstrate their research and development achievements.
