   Physics of the Sun    Stellar physics
and stellar activity
  Magnetic fields and turbulence in stars, accretion disks, and galaxies. Computer simulations of dynamos, magnetic instabilities, differential rotation, and magneto-convection; MHD laboratory astrophysics      Determination of the evolution of magnetic structures in the solar atmosphere with optical observations; coronal plasma processes studied by solar radio physics      Computer simulations of stellar physics such as stellar convection, winds and dust envelopes of red giants; determination of stellar surface parameters and chemical abundances. Observations of stellar activity by robotic doppler imaging and photometry.
 
 
 
  Selected projects
