Resume¶

I received my Ph. D. in Physics from the Autonomous University of Madrid (UAM) in 1986. Afterwards I worked abroad for a total of four years, 8 months at the University of Hamburg setting up a Raman spectroscopy laboratory, more than 2 years at the IBM Thomas J. Watson Research Center in New York, and 1 year at the Max-Planck Institute for Solid State Research in Stuttgart, in the last two cases studying the electro-optical properties of semiconductor nanostructures. Since 1988 I am a staff scientist at the Materials Science Institute of Madrid (ICMM-CSIC), first as a Research Associate and since 2006 as a Research Scientist (Investigador Científico).

Throughout my career I have investigated the optical properties of materials and I have published more than 128 papers and a few books.

While working in semiconductor superlattices at IBM, together with Prof. Emilio E. Mendez, we observed the formation of the Wannier-Stark ladder, whose existence had been the subject of a strong theoretical debate for nearly 40 years. We also measured the coherence length of electron states in semiconductor superlattices and observed for the first time a doubly resonant Raman effect induced by an electric field. I continued working at IBM and then at the Max-Planck (here with Profs. H. T. Grahn and K. Ploog) on the coupling of extended and localized electron states in semiconductor nanostructures.

In 1995 I started the Raman Microscopy Lab to study the nano- and microstructure of materials and devices. I have collaborated with many different groups on optical waveguides, semiconductor nanostructures, coatings and thin films, biological materials, ion and laser irradiation effects, etc.

I have also devoted some efforts to the dissemination of science by contributing to courses, books, book chapters, and popularization activities.
