I am a second-year Ph.D. student in Computer Science at the School of Computing (SoC), National University of Singapore (NUS), supervised by Prof. Xiaokui Xiao. Before joining SoC, I earned my B.Eng. degree in Computer Science from the Southern University of Science and Technology (SUSTech) in 2024. My prior research has focused on social network analysis and graph algorithms, e.g., influence maximization. I am currently interested in cost-efficient large language model (LLM) approaches.
