He received his Ph.D. in Physical Sciences under the supervision of J-Y. Bigot. His thesis was entitled “Optical properties of fluorescent protein studied by femtosecond spectroscopy”. After his Ph.D., he joined the group of Pr. B. von Issendorf at the University of Freiburg in Germany for one year to study the electron dynamics in metallic clusters by using pump-probe spectroscopy. In 2006, he was recruited as an Assistant Professor and is now working at the University of Strasbourg in the Laboratory of Biophotonics and Pharmacology. His main research is focused on understanding biomolecular interaction in living cells by using quantitative fluorescence microscopy. He is involved on a broad range of topics such as single molecule experiments, high-resolution fluorescence microscopy, and optical characterization of organic nanoparticles… He has published > 35 articles in international journals.
