About Me
I obtained my PhD degree from the University of Hong Kong under the supervision of Prof. Siu-Ming Yiu. Now I am a postdoc fellowship in Computing and Data Science at Nanyang Technological University, advised by Prof. Kwok-Yan Lam. During past several years, I also cooperated with Prof.Hongzhi Yin, Prof.Christian S Jensen and Prof. Pietro Lio.
Research Interests
My research focuses on LLM-driven time series, graph data mining, AI for biological science. I have conducted spatial-temporal data ming research (TKDE 2025, TKDD 2025, WWW 2023, ICML 2023, ICDE 2023), some research on time series (AAAI 2025) and efficient machine learning (Neurips 2025 and EMNLP 2025).
