Diego González Sánchez
Postdoctoral researcher
Alfréd Rényi Institute of Mathematics

I am a postdoctoral researcher at the Álfred Rényi Institute of Mathematics in Budapest under the supervision of Balázs Szegedy. My research interests include additive combinatorics and its relations with ergodic theory, probability and dynamical systems. I am also interested in the theory of convergence and generalization of deep neural networks.
