Didier Felbacq was born in June 1969 in Cambrai, France. He graduated in mathematics (agregation, 1993) and physics (Ecole Centrale Marseille, 1992). His PhD thesis was on the theoretical and numerical modeling of photonic crystals (1994). Since 2002, he has been a full professor of physics at University of Montpellier. He is involved in theoretical and numerical research in close collaboration with experimentalists. His current activities cover electron transport in transistors for TeraHertz emission and detection, second harmonic emission in photonic crystals, excitons in 2D materials, quantum metamaterials, thermal metamaterials, acoustic metamaterials and biophysics. Didier Felbacq is a former member of the Institut Universitaire de France.
