Really happy to see this out in PRX Life! There you can find an eco-evolutionary framework integrating the evolution of viral infectiousness and antigenic features. While the former determines contagion events among hosts, the latter tells us how quickly viruses can escape population immunity 1/4👇

Explosive adoption of corrupt behaviors in social systems with higher-order interactions

Human behaviors in social systems are often shaped by group pressure and collective norms, especially since the rise of social media platforms. However, in the

Social polarization promoted by sparse higher-order interactions arxiv.org/abs/2507.12325

Social polarization promoted by sparse higher-order interactions

Many social interactions are group-based, yet their role in social polarization remains largely unexplored. To bridge this gap here we introduce a higher-order framework that takes into account both g...

🚨 New preprint out!

Our latest work explores the interface between complex networks, epidemic spreading, and eco-evolutionary dynamics arxiv.org/abs/2506.03279

By a great team: @santiagolaot.bsky.social + Octavio Rotita + Alex Arenas + @sorianopanos.bsky.social + @gomezgardenes.bsky.social

Genotype networks drive oscillating endemicity and epidemic trajectories in viral evolution

Rapidly evolving viruses use antigenic drift as a key mechanism to evade host immunity and persist in real populations. While traditional models of antigenic drift and epidemic spread rely on low-dime...
