Ph.D. in Physics by the Universidad de Valencia and Ph.D. in Applied Mathematics by the UPV. “Catedrático”. Researcher at Instituto de Matemática Pura y Aplicada at UPV, and profesor at department of applied mathematics (DMA) at UPV. Lluis Miguel García Raffi, started his research activity in an institution devoted to Nuclear and Particle Physics, Instituto de Física Corpuscular (CSIC-UV). His research interest turns around three key points: research in Mathematics devoted to function approximation and modelling, research in Physics devoted to wave propagation in periodic media, phononic crystals and metamaterials, and nonlinear physics and mathematical modelling in teaching.
