About Me

I am a physicist and a PhD candidate at the University of Zaragoza. I am interested in modeling Complex Systems by capturing both their underlying structure and their dynamical mechanisms. I am particularly interested in systems where group (higher-order) interactions provide the natural representation, and in how the coevolution of different viral strains shapes epidemic outbreaks.

Here there is a list of my publications, the network of my coauthors, and information about my experience teaching and directing bachelor's and master's thesis.
