Research fields: Solar flares, EUV and X-ray emission originating from flares, coronal loops. Numerical modeling: hydrodynamics of flare and coronal loops, transfer and dissipation of energy of high energy particle beams in the solar atmosphere, hybrid codes - modeling of solar flares combined with radiative transfer. EUV and X-ray observations of solar flares: EUV and soft X-ray plasma diagnostics, high energy particle beams parameters from flare hard X-ray spectra. 1996 graduated in Astronomy and Astrophysics, 2002 PhD in Theoretical Physics, Astronomy and Astrophysics both from the Faculty of Mathematics and Physics of Charles University, Prague. Stays abroad: 1998 Goddard Space Flight Center in Greenbelt, USA, 2000 Max Planck Institute in Garching, Germany.
