About Me

I am a Postdoctoral Researcher at the Institute for Basic Science (IBS), where I have the privilege of working with Prof. Hong Liu in the Extremal Combinatorics and Probability Group. I am grateful for his guidance and support.

I received my Ph.D. in Mathematics from the University of Science and Technology of China in 2026, where I had the privilege of being advised by Prof. Jie Ma. His guidance has been foundational to my development as a researcher.

During my doctoral studies, I was a Visiting Student Researcher at the University of Warwick, where I had the opportunity to work with Prof. Oleg Pikhurko and benefit from his insights.

I have also benefited from discussions, collaborations, and support from Prof. Jun Gao, Prof. Tuan Tran, Prof. Zixiang Xu, Prof. Xizhi Liu, and Dr. Xinqi Huang, and I am thankful for the insights and encouragement they have shared with me along the way.
