NicolasLe Thomas
Nicolas Le Thomas received the degree in engineering from "Ecole National Supérieure de Physique de Grenoble" (ENSPG) in 1998 and the PhD degree from "Institut Polytechnique de Grenoble" (INPG) in 2002. He carried out the PhD thesis at CEA/Grenoble.

During 2002 and 2005, he was postdoctoral fellow at the University of Dortmund working on the optical spectroscopy of semiconductor nanocrystals. From 2005 to 2011, he was research associate at "Ecole Polytechnique Fédérale de Lausanne" (EPFL) working on the optical characterisation of photonic crystals structures. In 2012, he has been appointed professor in the Engineering Faculty of Ghent University.

His main interests include on-chip high-resolved microscopy, integrated photonic sensors, biological applications of sub-wavelength photonic structures, optical spectroscopy of nanostructures, and semiconductor lasers.
