·     Research

My research is focused on dynamical complex systems, which is a highly interdisciplinary research field. A main research line is on nonlinear photonics, and in particular, on nonlinear dynamics of semiconductor lasers. Main research goals are: i) advance our understanding of nonlinear phenomena for improving the robustness and reliability of laser systems (e.g., for suppression or control of ultra-high intensity pulses, referred as optical rogue waves) and ii) to exploit nonlinear phenomena for novel applications (such as optical neurons, all-optical square-wave switching, sub-wavelength position sensing, etc.).

Another research line is focused on the development of advanced tools of nonlinear time-series analysis, specific for the study of stochastic and high-dimensional complex systems, such as the Earth climate (weather refers to short-term variability while climate refers to long-term trends). Assessing climate similarities (teleconnections) via advanced statistical tools (ordinal symbolic analysis, complex networks) can: i) advance our understanding of atmosphere-ocean phenomena, ii) allow for climate model testing and inter-comparison and iii) improve climate predictions.

Semiconductor laser dynamics and climate time-series analysis might appear to be unrelated research fields, however, they are not. The dynamics of semiconductor lasers when they are under the influence of external perturbations that involve time-delays (for example, optical feedback) is not only stochastic but also high-dimensional, and thus, semiconductor lasers can be used as “toy models” for testing novel tools of nonlinear time-series analysis in empirical data that can be recorded under fully controllable conditions.

·     Teaching

I teach undergraduate courses at the Escola Tècnica Superior d’Enginyeries Industrial i Aeronàutica de Terrassa (ETSEIAT) and graduate courses at the Master Program in Photonics offered by UPC, UAB, UB and ICFO. Read more about my teaching activities (including lecture notes).

·     PhD students

Current PhD students: Taciano Sorrentino, Juan Ignacio Deza, Giulio Tirabassi and Carlos Quintero.

·     Biography

I received my Bachelor (1989) and MSc (1991) degrees in physics from Universidad de la República, Uruguay. I received my PhD (1999) degree in physics from Bryn Mawr College (BMC), Pennsylvania, USA. My PhD thesis was on Nonlinear Dynamics in Semiconductor Lasers with Optical Feedback, supervised by Prof. Neal B. Abraham. Find here pictures of my graduation at BMC

Before joining UPC in 2004, from 1986 to 2004 I was Associated Professor at the Instituto de Física, Facultad de Ciencias, Universidad de la República, Uruguay, where I still have many friends and collaborators (you might have noticed that I keep my home page in Uruguay). At UPC I was a Ramon and Cajal researcher (2004-2009) before becoming Associated Professor.
