I am currently a Postdoctoral Researcher at City University of Hong Kong (CityUHK), working with Prof. Dapeng Wu. Previously, I was a Postdoctoral Researcher at The Hong Kong University of Science and Technology (HKUST). I received my Ph.D. in Computer Science from The University of Sydney (USYD), advised by A/Prof. Wei Bao and Prof. Albert Y. Zomaya. I also received my Master’s degree in Information Technology from The University of Sydney and my Bachelor’s degree in Information Technology from Queensland University of Technology (QUT). Beyond academia, I have several years of industry experience in cloud-based systems and software development, including serving as a Technical Lead at Link Group Pty Ltd, Australia.

My research focuses on federated learning, distributed machine learning, weakly supervised learning, and MLLMs, with particular interests in improving the efficiency, trustworthy, and generalizability of learning over edge, cloud, and multi-tier networks. I have published 20+ papers at the top journals and international conferences such as NeurIPS, TIP, TPDS, TDSC, TSC, TNNLS, and ICDCS.
