András Mészáros

I am a Brauer Postdoctoral Fellow at University of Toronto Scarborough, Department of Computer and Mathematical Sciences mentored by Bálint Virág.
I obtained my PhD at Central European University in 2021. My advisor was Miklós Abért.
I was also a junior researcher at Alfréd Rényi Institute of Mathematics.

Research interest: Random matrices, graphs and simplicial complexes; Graph limits; Algebraic and spectral graph theory; Random processes on graphs
