Brief Biography

I am an Assistant Professor at the Data Science and Analytics Thrust, Information Hub, The Hong Kong University of Science and Technology (Guangzhou). I also hold an affiliated position at the Hong Kong University of Science and Technology, the Clear Water Bay campus at Hong Kong. I received my Ph.D. degree in Computer Science from Tsinghua University in 2023, under the supervision of Prof. Guoliang Li.

My current research interests include AI for Data Analytics (e.g., NL2SQL, TableQA, AI4VIS) and Data-centric AI.

I am actively seeking self-motivated PhD students (Spring/Fall 2025). If you are interested in working with me, please send an email with your CV and transcripts for all degrees.
