I am currently a postdoctoral researcher in the Combinatorial group at the Institute of Computer Science of the Czech Academy of Sciences, working with Jan Hladký on the Czech Science Foundation (GAČR) EXPRO Project "Graph limits and beyond". Previously, I was a PhD student at the Department of Mathematics of the London School of Economics and Political Science under the supervision of Julia Böttcher and Peter Allen.
My research interests include extremal and probabilistic combinatorics. I have worked on problems in extremal graph theory and random graphs.
