Prof. Cristina Masoller research on complex systems and data analysis

Complex systems are constituted by a large number of nonlinear units with nonlinear interactions. The dynamics and the interactions are often only partially known, and we are interested in developing appropriated data analysis tools for inferring and predicting the system’s structure and dynamics, from observed data. We are also interested in the identification and forecast of critical transitions and extreme fluctuations.
