Gérard COLAS des FRANCS was born on July 4th, 1973 in L'Union, France. He is  professor (PR2) at the Université de Bourgogne. He holds a doctorate in Physics (2002) from the University of Toulouse, where he worked on fluorescence in a surface-tip junction. He then moved to University of Münster as a Marie Curie fellow where he investigated highly resolved optical near-field microscopy. His interests are focused on the fundamental aspect of surface enhanced spectroscopies, plasmonics, and near-field optics. He is currently supervising 2 PhD students (HDR, Nov. 2009) and 2 Postdoc. He received the PES (prime d’excellence scientifique) in 2010. GCF is author or co-author of more than 70 scientific publications, and 2 book chapters.
