Position Principal Investigator
Group Complex Systems
Corral Cano, Alvaro
Biosketch

I coordinate the CRM Complex Systems Group, whose research is addressed to understand complex systems. Our 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. We have found statistical physical-like laws in several of these systems. Our results have been communicated to society through newspapers, radio, and TV.

 

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

I (try to) lead the network complexitat.cat.
