About Me

I am currently an associate professor at the School of Artificial Intelligence at Sun Yat-sen University. I also serve as deputy director of the Guangdong Provincial Engineering Technology Research Center for Data Element Development and Utilization. I received my Ph.D. in Computer Science and Engineering from the Hong Kong University of Science and Technology (HKUST), where I was advised by Prof. Lei Chen.

Research Interests

My research focuses on urban computing, LLMs and AI agents for smart cities. My group collaborates with researchers at HKUST, The Hong Kong Polytechnic University (PolyU), Tsinghua University, and Tongji University.
