Research Framework

My primary research fields are solar and stellar physics with additional interests in extra-solar planets. I worked on a large number of complementary topics relevant to these fields. In particular, I have focused on the structure, dynamics, and energy balance of the solar atmosphere, including the structure, evolution, and generation of magnetic fields, which are of fundamental importance for stellar activity and the processes behind it. Further topics range from the effects of non-equilibrium ionization and molecule formation in the Sun towards first experiments for cool dwarf stars. Due to the complexity of these topics, I pursue two complementary approaches:
(i) Realistic numerical simulations in comparison with space-borne and ground-based observations and
(ii) numerical experiments and simplified simulations for individual physical processes.
