About Me

Hello! I am a PhD student in mathematics working in extremal combinatorics and graph theory, with a particular interest in graph homomorphism inequalities.

News

I am visiting Caltech from January to July 2026, hosted by David Conlon.

During my visit, I’ll be in the U.S. and would be happy to consider invitations for seminars or research meetings; please feel free to contact me.
