Since 1994: researcher at LESIA, a department of the Paris Observatory.
Main fields of interest:
physics of plasmas (collisional and collisionless plasmas)
fluid dynamics (compressible and incompressible)
space and astrophysical plasmas
solar atmosphere and solar wind
planetary magnetospheres
environment of artificial satellites
gravitationally stratified plasmas
dynamos
physics of granular systems
Methods:
