Personal Information
I am a researcher at the CRM Complex Systems Group. My research has been addressed to describe, model, and try to predict the behavior of complex systems. The approach has been diverse: theoretical, computational, experimental, and analysis of observational data. Main systems of interest are natural hazards (earthquakes, hurricanes, rain…) and communication systems (human language, music…), paying special attention to the necessary statistical tools. Together with my colleagues, we have found physical-like laws in several of these systems, and we have published our results in physics, geophysics, geology, and cross-disciplinary-science journals. Our results have been communicated to society through newspapers, radio, and TV. In the meantime of all this I got a PhD in Physics, a post-doc in Denmark, and a Ramón y Cajal fellowship back in Spain. Currently, I coordinate the CRM Complex Systems Group. The rest of the team members are:

Irina Espejo (undergraduate student)
Víctor Navas (predoctoral researcher)
Isabel Moreno Sánchez (predoctoral researcher)
Oliver Planes (master project)
Isabel Serra
(postdoctoral researcher)


Indeed, I am very interested in the training of researchers, at the undergraduate, master, and doctoral level, having organized several summer schools in recent years.
