Biography

I am an LLM Researcher at Sea Group, Shopee LLM Team. I received my Ph.D. in Computer Science from Nankai University, jointly trained with Nanyang Technological University, Singapore, as a member of the Nankai-Baidu Joint Lab (NBJL). I was previously a research intern at Microsoft Research Asia, working on time-series LLMs. My research interests include Code LLMs & Agents, AI for Data Compression, and High-Performance Computing, with 30 publications at venues including KDD, AAAI, WWW, ACL, CVPR and Bioinformatics. Most of my tools are open-sourced on GitHub. Please feel free to reach out if you are interested in my research.
