The research activities of my group span a broad range of topics in modern astrophysics, from numerical modelling and physics of stellar atmospheres to quantitative spectroscopy, nucleosynthesis, and studies of chemical and dynamical structure of the Milky Way and star forming galaxies.

Our cutting-edge is non-equilibrium (Non-LTE) radiative transfer modelling using 3D convective atmospheres. Lifting the canonical approximations of 1D-geometry, hydrostatic equilibrium and local thermal equilibrium, our models open new avenues for studies of physics and structure of stars.

We are actively involved in major large-scale astronomical programs: the Gaia-ESO survey, WEAVE, PLATO, 4MOST, and MSE.  

With exquisite quality multi-million datasets, novel 3D Non-LTE models, and diagnostic methods, fundamentally new perspectives are opening in studies of the origins of chemical elements, stellar clusters, binaries and multiplicity, Galactic structure and extragalactic stellar populations, and star-planet connection.

Among various topics, we tackle the following questions:
