Jun Gao

I am currently a postdoctoral researcher at the University of Warwick, UK, working with Professor Oleg Pikhurko.

From August 2022 to April 2025, I was a research fellow in the Extremal Combinatorics and Probability Group, led by Professor Hong Liu, at the Institute for Basic Science (IBS) in Daejeon, South Korea.

Prior to that, I completed my Ph.D. in the School of Mathematical Sciences at the University of Science and Technology of China (USTC), under the supervision of Professor Jie Ma. I received my B.S. degree in 2017 from the School of the Gifted Young at USTC.

Research Interests:

I am interested in Combinatorics, Graph Theory (both extremal and structural), Extremal Set Theory, Discrete Geometry, and their applications to Computer Science.
