Biography

I am a team leader at Centai. My interests are nonlinear dynamics and stochastic processes on top of complex networks and structured populations. More specifically, I am focusing on epidemic and rumor spreading in single and multilayer systems. Additionally, I am concerned about the structural characterization of multilayer networks, mainly through spectral theory. Recently, I am also involved in the study of higher-order interactions and hypergraphs, both from the structural and dynamics viewpoints. If you need further information, please don't hesitate to contact me.
