Dr. Juan Ramón Sánchez Valencia is a Physicist and Materials Engineer. He developed his Ph.D. at the Institute of Materials Science of Seville (CSIC-Univ. Seville), that was defended in 2010. Then, he started his postdoc at EMPA-ETH Dübendorf (Switzerland) about the fabrication of atomically-precise carbon-based nanomaterials. Since 2014 he is a researcher at the Institute of Materials Science of Seville, where he obtained a Marie Skłodowska-Curie action, a project financed by University of Seville and, recently, a “Ramon y Cajal” 5-year national contract. His research is focused on the fabrication and characterization of functional nanomaterials for advanced applications such as photonic, electronic and energy harvesting
