Giovanni Petri is a Principal Researcher at CENTAI, and a Guest Scholar at IMT Lucca. He is a theoretical physicist that shortly after graduating decided that complex systems – in the broadest sense – were more intriguing than cosmology. He fell in love with the idea of high-order interactions, of emergent properties and ended up earning a PhD on complex networks at Imperial College London in 2012. Theoretical approaches never stopped fascinating him, and he continues this research today working at the interface between complex systems and algebraic topology. His research spans the analysis of neuroimaging data and AI systems with topological techniques, the formalization of cognitive control models with tools of statistical mechanics and network theory, and the study of the predictability of socio-technical systems.
