    CV

    Doctor in atomic physics

    age : 30 , french

     

    Professional experience

     

    Since september 2013: “Atom interferometry gradiometer for the determination of the Newtonian gravitational constant G” at INFN and LENS, Florence, Italy.

     

    I presently work on the metrological experiment MAGIA, which has recently measured the Newtonian constant with a relative uncertainty of 10-4. I am developing a new large area gravity gradiometer in order to increase again the sensitivity of the experiment toward the gravitational waves detection limit.

     

    2011 - 2013     (2 years): European Space Agency (ESA) Post-Doc: “SAI, Space Atom Interferometer”: Florence, Italy.

     

    I was responsible of the experimental development of the SAI project, led the European Space Agency which coordinates 9 laboratories of excellence in Italy, France and Germany. The SAI project investigates both experimentally and theoretically the various aspects of placing atom interferometers in space: the equipment needs, the realistically expected performance limits and potential scientific applications in a micro-gravity environment. I have demonstrated in the laboratory that the SAI prototype is able to perform space atom interferometry successfully.

     

    2007  (3 years)  Doctorate thesis: “Atom Gravimetry: Improvement of Accuracy and New Geometries”, with highest distinction (très honorable), at Université Pierre et Marie Curie, Paris 6, and Observatoire de Paris – SYRTE.  Grant delivered by the CNRS and by the CNES.

     

    The goal of the absolute gravimeter of the Observatoire de Paris - SYRTE is to measure the gravitational acceleration with a relative accuracy of 10-9for the metrological "watt balance" project, led by the Laboratoire National d’Essai (LNE). During my thesis, we developed a new vacuum chamber, which allowed us to evaluate the limiting systematic errors. The gravimeter uses atom interferometry, where a cold cloud of 87Rb atoms in free fall is manipulated thanks to two-photon transitions. We reduced the measurement uncertainty below the goal, except for laser wave-front aberration effects. In parallel, we developed three new methods of atom interferometry measurement for space fundamental research and on-board applications.

     

    2007  (6 month) Master 2 training period: nano-robots fabrication, Laboratoire de Photo-Physique Moléculaire, LPPM, Orsay.

     

    This consisted in the manipulation of nano-sticks with the tip of an Atomic Force Microscope.

     

     

    Education

     

    2010    Ph.D. in atomic physics at Université Pierre et Marie Curie UPMC Paris 6 carried through the Observatoire  de Paris – SYRTE (Space Time Reference System) in the research group of A. Landragin:  “atom interferometry and inertial sensor”.

     

    2007      Master: atoms and molecules experimental physicsat UPMC

     

    2006      Bachelor: fundamental physics at UPMC

     

    2004      Two years diploma (french Deug): Mathematics at UPMC

     

    Professional skills

     

    Skills:   atomic gravimeter - gradiometer - atom cooling - laser physics - optics - inertial sensors - physics test with space interferometers - atomic clocks - interaction light matter - electric fundamental metrology - seismology - european project coordination                

     

    Language:    french, english, italian, german (basic)

     

    Softwares:     matlab, origin
