I am the head of the Extremal Combinatorics and Probability Group (ECOPRO) and a distinguished research fellow (首席科学家) at the Institute for Basic Science (IBS).

Previously, I was a faculty and a UKRI Future Leaders Fellow at the Mathematics Institute at University of Warwick. Before that, I was a Leverhulme Early Career Fellow, working with Oleg Pikhurko. I got my Ph.D. in 2015 at University of Illinois at Urbana Champaign, advised by Józsi Balogh.


I am interested in extremal and probabilistic combinatorics, graph theory, discrete geometry, Ramsey theory and combinatorial number theory.

For some of my recent work, see this blog post on Erdős and Hajnal’s odd cycles problem and this interview on the clique minimisation problem.
