Philippe Lalanne is Directeur de Recherche at CNRS and is an international expert in nanoscale electrodynamics. He was first involved in Optical Information Processing in the group of Pierre Chavel at l'Institut d’Optique. In 1995, he spent a sabbatical year in the group of G.M. Morris, at the Institute of Optics in Rochester.

With his colleagues, he has launched new and powerful tools in computational electrodynamics [JOSAA 13 (1996) & JOSAA 18 (2001)], new type of diffractive optical elements with unprecedented efficiencies [J. Opt. A: Pure Appl. Opt. 4, S119 (2002)], has provided a deep insight into the physical mechanisms used in light confinement in ultrasmall photonic-crystal cavities [Nature 429 (2004)], has evidenced the importance of quasi-cylindrical waves in the optical properties of subwavelength metallic surface [Nature Phys. 2 (2006) & PRL 98 (2007)], to further elaborate a microscopic theory of the extraordinary optical transmission explaining the role of plasmons in this phenomenon [Nature 452 (2008) and Nature 492 (2012)].

He has co-authored about 140 publications in peer-reviewed journals and filled 7 patents. He is a recipient of the Bronze medal of CNRS, the prix Fabry de Gramont of the Société Française d’Optique; he is a fellow of the IOP, OSA and SPIE and was Carl Zeiss visiting Professor at Jena in 2010. He was the supervisor of 10 PhD candidates, has co-supervised 5 PhD candidates.

He is currently working on computational electrodynamics, slow light, quantum plasmonics, and solar energy management.
