I received my Ph.D. in Management Science and Engineering from the School of Computing and Artificial Intelligence (SCAI), Shanghai University of Finance and Economics (SUFE), in 2026, advised by Prof. Yun Chen. During my Ph.D., I was also a visiting student at Southern University of Science and Technology (SUSTech), working with Prof. Guanhua Chen.
I am actively looking for full-time research positions (industry or academia). Feel free to reach out via email.
