Gérard COLAS des FRANCS was born on July 4th, 1973 in L’Union, France. He is  full professor (PR1) at the Université de Bourgogne. Alumni of ENS Cachan (1994). 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 quantum plasmonics. He has supervised 8 PhD students (past and running, Habilitation Nov. 2009). He received the PES (prime d’excellence scientifique) in 2010. GCF is author or co-author of about 110 scientific publications, and 3 book chapters.

Gérard COLAS des FRANCS was born on July 4th, 1973 in L'Union, France. He is  full  professor (PR1) at the Université de Bourgogne. Alumni of ENS Cachan (1994). 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 quantum plasmonics. He as supervised 8  PhD students (past and running, HDR, Nov. 2009). He received the PES (prime d’excellence scientifique) in 2010.
