I am a Ph.D. student in the PolySmart Group at the Department of Computing of The Hong Kong Polytechnic University (PolyU). My research is co-supervised by Prof. Qing Li and Prof. Xiaoyong Wei. I obtained my Bachelor’s degree with First Class Honours from PolyU in 2025.
My primary research interests are in domain-specific large language models (LLMs) and natural language processing (NLP). I have also contributed to other AI-related research projects, including applications in AI for Science.
