I'm a member of the cold-atom team.

Main current projects:

  • Intensity correlations for astrophysics (since 2015)
  • Cooperative scattering of light in cold atoms (since 2013)
Main past projects:
  • Random laser in cold atoms (2007-2016)
  • Photonic properties of ordered cold atoms: band gaps and DFB laser (2010-2012)
  • Lévy flights of light in hot vapors (2008-2009)
  • Bose-Einstein condensation and atom laser (2003-2007)
