José A. Sánchez Gil is Research Professor at the Instituto de Estructura de la Materia (CSIC). He graduated and received his PhD degree in physics from the Universidad Autónoma de Madrid in 1988 and 1992, respectively; the latter under the guidance of Prof. Manuel Nieto Vesperinas, working on rough surface scattering at the Instituto de Óptica (CSIC). He spent two years (1993-1994) as a post-doctoral fellow in the Physics & Astronomy Department of the University of California, Irvine (USA), in the group of Prof. Alexei A. Maradudin, involved in the theory of weak localization phenomena of bounded waves (surface plasmons and guided waves). In 1995 he joined the Surface Spectroscopies group at the Instituto de Estructura de la Materia (CSIC) as Associate Researcher developing the Plasmonics & Surface-Enhanced Raman Scattering theoretical research lines, becoming permanent research staff in 2000, and Scientific Researcher in 2008. During his career he has spent time at the Imperial College (London, UK), CICESE (Ensenada, México), FOM-Institute AMOLF (Amsterdam, The Netherlands), and ICD-LNIO Université de Technologie de Troyes (France). He leads the theoretical division of the Enhanced Spectroscopies on Metal & Semiconductor Nanostructures (EON) group. His current research interests are in the areas of nanophotonics, plasmonics, and metamaterials, in connection with plasmonic nanoantennas, semiconductor nanowires, and hybrid nanostructures.









Objectives:

Theoretical research of the electrodynamic response of a variety of metallic & all-dielectric nanostructures, isolated or in planar arrays (metasurfaces), with special emphasis on the impact of the plasmon and Mie resonances on the emergence of exotic modes and bound states in the continuum. Implications of enhanced local electromagnetic fields, not only in SERS and SEF, but also exploring fascinating light-matter interaction phenomena at the nanoscale such as lasing, strong coupling, or chiral sensing.
