Biography
I was born in Vitry/Seine in Paris area in 1968. I studied at the University of Orsay Paris XI then Paris VI where I specialized in Physico-Molecular Chemistry. I completed my doctoral thesis in the inorganic chemistry field at the interface with biology. I worked on the synthesis and study of polyimidazole complexes of iron and copper, models of active metalloprotein sites under the direction of J-C Chottard. After a post-doctorate in biochemistry and molecular biology at New York University with W.T. Mcallister and at Pasteur Institute under the direction of H. Buc, I joined the Physics Laboratory (UMR5672) of the Lyon ENS in 2000. I continued research at the interface of Physics and Biology. My course allowed me to work in various environments (chemistry, biology, physical), enrich my scientific culture and develop a scientific activity at the interface of these areas.Research topics
My scientific interest is in the dynamics of biological objects. The originality consists in not treating them as a whole but in individually analysing their future using video-microscopy techniques of unique molecules or cells. My main research theme is the understanding of transcription mechanisms and their consequences on cell differentiation. For this reason I am interested in understanding the transcription mechanisms whether in an isolated in-vitro system or in the in-vivo cell. In the Physics laboratory and then in the Joliot-Curie laboratory, I developed experiments based on the observation by microscopy of fluorescence of enzymes and unique DNA in interaction.More recently, the development of high-resolution microscopies has made it possible to resolve the position of proteins in the nucleus with a localization accuracy of 20 nm despite the protein overload. I then initiated a collaboration to report the activity of HOX transcription factors in the living cell. In parallel with this activity, the use of TIRF (Total Internal Reflection Fluorescence) microscopy has allowed me to track biological objects such as podosomes or microtubules and to report on their dynamic properties.
