Iridescences

Serge Berthier teaches physics at the Denis Diderot-Paris 7 University and researches biologic structures, colors and biomimetism at the Institut des NanoSciences de Paris ( Pierre and Marie Curie-Paris 6 University and CNRS). He teaches solid state optics in the post-graduate degree "Optics and material" and the post-graduate research degree "Optics and Photonic" for the Denis Diderot University. He also teaches electromagnetism and laser physics to undergraduates at the Paris-Jussieu Institut of Technology.
