Prof. Cristina Masoller research on complex systems and data analysis

Complex systems are non-linear systems made up of a large number of interacting units.

 

Our research focuses on characterizing and predicting the behavior of complex systems using appropriate data analysis tools. We are interested in identifying early warning indicators of upcoming extreme events or critical transitions.

 

Watch the videos to see how the how seasons evolve during a normal year, a El Niño year and a La Niña year (temporal evolution of the cosine of the Hilbert phase, D. Zappala et al., Chaos 2020).
