About Me

I’m a second-year Ph.D. student at Academy of Mathematics and Systems Science, Chinese Academy of Sciences, supervised by Prof. Ya-xiang Yuan. Before that, I received my B.S. degree from Peking University in 2024, advised by Prof. Zaiwen Wen.

Research Interests

My research interests focus on numerical optimization, with an emphasis on both theoretic foundations and algorithm development. Recently, I have been working on Learn to Optimize (L2O), particularly on developing data-driven algorithms for solving combinatorial optimization algorithms.
