As a Ph.D. student (1998-2003) at the Universidad Autónoma de Madrid under the supervision of Prof. J. Sánchez-Dehesa  (currently at the Universidad Politécnica de Valencia, Spain), my research work consisted in simulating the optical properties of opal-based photonic crystals and analyzing the subsequent numerical results. Both tasks involved an intense interaction with the experimental groups that fabricated and characterized the samples. In addition to calculations on demand, I conducted the classification of photonic bands by means of group theory and contributed to unconventional proposals for obtaining opal-like photonic crystals with a diamond lattice. I defended my Ph.D. dissertation on February 20th, 2004 and obtained the highest mark as well as the Outstanding Ph.D. Dissertation Award of my alma mater.

During my postdoctoral years, I tried to broaden my horizons at nanophotonics by consecutively focusing at some of its most recently exciting topics, namely surface plasmon-polaritons (SPPs), photonic metamaterials and optical nanoantennas:

In the course of my collaboration (2004-2010) with Prof. L. Martín-Moreno, a world-leading expert on the theory of SPPs, my efforts were devoted to the fundamental aspects of the interaction between SPPs and metallic nanostructures. Besides my acquiring of new computational and analytical skills, I was given the opportunity to join forces with top-ranked experimental groups in the field, such as Prof. Bozhevolnyi’s, and Prof. Ebbesen’s. As a main achievement, we obtained a remarkably simple scheme to modulate the SPP coupling-in at a real back-side illumination experiment. Our proposal was published in Nature Physics and a subsequent paper stemming from that work was then selected within The New J. Phys. Best of 2008.
 
From mid-June 2010 to October 2012, I was a post-doc of Prof. J.A. Sánchez Gil at the Instituto de Estructura de la Materia (CSIC). In that period, I focused my research on the complex electromagnetic response of individual nanoparticles mediated by their localized plasmon resonances. More precisely, I contributed to the proposal of a new strategy to obtain photonic metamaterials by means of metallo-dielectric core-shell nanospheres. I also led research work on plasmonic Fano-like interference at rod-shaped nanoantennas. This last topic resulted in two papers appearing in New. J. Phys. and ACS Nano, respectively. The former, which was selected within the Feb. 2012 monthly highlights of the publishing journal, focuses on the physical mechanisms underneath plasmonic Fano-like interference, whereas the latter presents a theoretical proposal for its application in refractive index sensing.

In November 2012, I rejoined the Universidad de Zaragoza, where I currently hold a position as an Associate Professor of Condensed Matter Physics (tenured) at the Escuela de Ingeniería y Arquitectura. From then on, in addition to my teaching duties, I continue to work on problems related to the interaction of electromagnetic radiation with all sorts of nanoparticles.
