I’m honored and happy to receive the EPS-SNPD prize.
Congratulations to my fellow awardees, I’m humbled to be in their company.

Science is a team sport, and I’m infinitely grateful to my colleagues, collaborators, and students. This is a recognition to our team work.

I’m grateful and energized🙏
Congratulations to @alexvespi.bsky.social for being awarded the EPS SNPD Prize 2025, in recognition of his seminal contributions to the statistical physics of complex networks and for unveiling the universal principles governing epidemic spreading and information diffusion.
