NicolasLe Thomas
Nicolas Le Thomas received the degree in engineering from "Ecole National Superieure 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 researcher at "Ecole Polytechnique Federale de Lausanne" (EPFL) working on the optical characterisation of photonic crystals structures. In 2012, he was appointed professor at the Faculty of Engineering at Ghent University.

His main interests include photonic integrated circuits for UV applications, optical microscopy, integrated photonic sensors, Raman spectroscopy, and semiconductor lasers.
