I am interested in dynamical complex systems: systems that evolve in time, which are composed by interacting nonlinear elements.


The main goals of my research are 1) to exploit complex phenomena for novel applications and 2) to develop novel data analysis tools for complex signals.


Semiconductor lasers, neuronal excitability, complex networks and climate data analysis might seem, at first sight, unrelated research topics; however, semiconductor lasers can generate spiking output signals with a wide range of time-scales which resemble neuronal spikes; hence, the laser experimental setup allows recording large datasets under controlled conditions, which in turn allow testing the data analysis tools that we routinely use for the analysis of real-world signals.
