### External Fellow

I am an associate professor at the Physics Institute of the Federal University of Rio Grande do Sul (UFRGS) in Brazil. Before joining UFRGS, I spent several years as a postdoctoral researcher in Belgium, Italy, and Brazil. My research interests lie in the statistical mechanics of disordered systems composed of many interacting elements (atoms, neurons, social agents, etc.). The disorder manifests itself in the random interactions, and the tools of statistical mechanics have to be properly adapted in order to study the macroscopic behaviour of these systems. Within the vast field of disordered systems, I have been working on problems at the interface between random matrix theory, spin-glasses, random graphs, and Anderson localization. More recently, my research has been focused on refining and adapting the techniques of random matrix theory to understand the spectral properties of complex networks.
