Biography

I am currently a Research Fellow in the School of Computing (SoC) at the National University of Singapore (NUS), advised by Prof. Xiaokui Xiao. I obtained my Ph.D. degree at The Chinese University of Hong Kong in 2023, under the supervision of Prof. Sibo Wang. Previously, I received my B. Eng. from School of Electronics and Information Technology, Sun Yat-sen University in 2019.

My research interests include approximate algorithms with theoretical guarantees, AI for databases, and representation learning.
