Research



Our aim is to develop data-driven computational models of complex socio-cognitive systems. We work to develop innovative mathematical models and computational tools to better understand, anticipate and control massive social phenomena with a complex systems approach. The focus is on information and misinformation spreading and their effect on opinions. Our recent findings showed the pivotal role of confirmation bias on informational cascades online as well as the inefficacy of debunking in contrasting misinformation spreading.
