Fields of Research
Dynamical atmospheres and convection in asymptotic giant branch stars:
- Development of a frequency-dependent radiation-hydrodynamics code
- Detailed radiative transfer for dynamic atmospheric structures
- Comparison of models with observations (spectra, colours, line profiles)
- 3D radiation-hydrodynamical 'star-in-a-box' models

Modelling of dust driven mass loss from long-period variables:
- Interaction of pulsation and mass loss
- Time-dependent dust formation and wind dynamics
- Influence of molecular and grain opacities
- Dependence of mass loss on stellar parameters
- Observable properties of circumstellar dust shells
- Non-spherical winds due to slow stellar rotation
