About Me

I am a Ph.D. student at the Data Science and Analytics Thrust, Information Hub, The Hong Kong University of Science and Technology (Guangzhou). Currently, I am a member of the DIAL, supervised by Prof. Nan Tang and co-supervised by Prof. Yuyu Luo.

I focus on LLM-based application research. Below are some stunning topics I am working on: (1) Good Data For AI: data cleaning and transformation, see MegaTran; (2) Good AI For Fund Investment: Project Leader on DeepFund.
