Bernard Plaçais received the physicist degree from the Ecole Supérieure de Physique et Chimie Industrielle and the master in solid state physics from Sorbonne University in 1980. He obtained the PhD degree and Habilitation diploma from Sorbonne University in 1983 and 1990. He is research director at Physics Institute of CNRS (centre national de la recherche scientifique) and works since 1983 at the Laboratoire de Physique de l'Ecole Normale Superieure (UMR 8023 of the CNRS). In 2000, he created the Mesoscopic Physics group which he is heading. From 2010 to 2017 he was director of the french Quantum Mesoscopic Physics network (GDR 2425 of the CNRS). He is partner of the Graphene Flagship and editorial board member of J. Phys. Materials. He is member of the selection panel of the European MicroKelvin Platform. His interest covers quantum mesoscopic transport, electron quantum optics, quantum Hall effect, quantum materials including graphene, 2D materials and topological insulators, and vortices in superfluids and superconductors. He has authored 110 publications and supervised 20 PhD thesis.
