Roberto Sastre (1944-2010) received his Ph.D. in Chemistry from the Universidad Complutense de Madrid, Spain. He was Professor of Research at Consejo Superior de Investigaciones Científicas (CSIC), in the Instituto de Ciencia y Tecnología de Polímeros, Madrid. He was also a visiting scientist at Catholic University of Lovaina, Belgium; Institute of Macromolecular Chemistry, Prague, Czechoslovakia; Ecole National Superieur d’Arts et Matiers, Paris, France, and Universidad Católica de Chile, Santiago de Chile. Roberto Sastre authored more than 200 papers in refereed journals and over 20 patents. His research focused on: photophysics and photochemistry of polymers and photoinitiators of polymerization, biomaterials, organic chemistry, synthesis and characterization of optical materials, holograpic recording in photopolymers, laser ablation of materials, and solid-state dye lasers.
Towards the end of his career Professor Sastre's research
was more focused on technological applications, and made significant
contributions to the development of organic-inorganic hybrid materials for
optoelectronic (bulk solid-state and waveguide lasers based on dyes
incorporated into nonanostructured media) and biophotonic (dental bone
