Balázs Szegedy

Research Professor and Head, Artificial Intelligence Research Department, HUN-REN Alfréd Rényi Institute of Mathematics

Dr Balázs Szegedy is a Research Professor and Head of the Artificial Intelligence Research Department at the HUN-REN Alfréd Rényi Institute of Mathematics. He is a world-renowned expert on the mathematical theory that evolved from the Szemerédi Regularity Lemma, which describes the behaviour of very large structures using mathematical tools.

Dr Szegedy is currently working on various topics related to the limits of discrete structures, a field connected to combinatorics, ergodic theory, and probability theory. He also studies the properties and invariants of physical networks, including new physical analogues of the Erdős–Rényi and preferential attachment models, as part of the EU-funded DYNASNET project, which aims to build a mathematically sound theory of dynamic networks.

Dr Szegedy has made significant contributions to higher-order Fourier analysis and, in collaboration with László Lovász, developed the theory of graph limits. His work has been recognised with several prestigious awards, including the Géza Grünwald Commemorative Prize (2002), the European Prize in Combinatorics (2009), a Sloan Research Fellowship (2010), the Fulkerson Prize (2012, jointly with László Lovász), and the Coxeter–James Prize (2013).
