Biography

I am a second-year PhD student at University of Arizona, advised by Prof. Lei Cao. I received my B.Eng degree at Sun Yat-Sen University in 2022. After that, I worked at Tencent CDB/TDSQL-C team as a software engineer for two years. I am also fortunate to start my first research journey with Prof. Qizhen Zhang.

My research interests include Agentic Data Systems, Cloud Database Systems, and LLM for Data Analytics.
