My research interests include noise fluctuations and stochastic processes, non-linear dynamics in semiconductor lasers, synchronization of coupled oscillators, delay effects in lasers and optolectronic systems, synchronization of chaotic lasers and encoded communications, pattern formation, quantum fluctuations in nonlinear optical cavities, noise-sustained structures, dynamics of localized structures, use of dissipative solitons
for information processing, generation of
high spectral purity microwaves
with opto-electronic oscillators, coupled
multiple delays, systems with state-dependent
and, more recently, the study of human mobility using geolocated
data and the socio-technical systems.
