Biography
Directeur de recherche CNRS (DR2). PhD in Physics in 1999, Université Pierre et Marie Curie, Paris. In 2000, post doc with Pr. M.A. Duncan, University of Georgia, USA. CNRS researcher since 2001. From 2001 to 2014, member of the Laser Physics Lab, CNRS/Université Paris Nord. Former head of the national network CNRS “Isolated and solvated Molecular systems” and former group leader “Biomolecules and Spectroscopy” (LPL, Univ. Paris Nord). Since 2015, member of the Institute of Molecular Sciences Orsay, CNRS/Université Paris-Saclay. Actual head of the research network CNRS “CPPS : Chimie Physique Paris Saclay”.
Expectations for WRHI
Exciting collaboration with Pr. Masaaki Fujii’s group, world expert in laser spectroscopy of molecular clusters and biomolecules. Combining their expertise in steady-state spectroscopy done at WRHI with time-resolved spectroscopy performed in my group at Université Paris-Saclay.
Research Projects
-
Cryogenic Laser Spectroscopy of Biomolecules
Developing state-of-the-art laser spectroscopies (energy and time resolved) for the study of biomolecular ions and their complex in the gas phase. Investigation of the structure and the photochemistry of complex biomolecular systems in well-controlled environment (cold temperature, energy, multiscale dynamics over 10 orders of magnitude).
