Thèmes de recherche
hase of cloud droplets and wet particles represents a medium where efficient chemical reactions can occur that lead to the modification of the composition of aerosol particles, cloud/rain water and the surrounding gas phase. Less attention has been given to the role of biological processes that occur in clouds. Microorganisms, such as bacteria, cannot not only act as IN but they also utilize organic substrates in cloud droplets and transform them into CO2 and other products, in competition to chemical processes. Thus, in order to understand the formation, evolution and radiative impact of clouds interdisciplinary efforts are needed to improve upon the description of relevant processes on all scales.
My research focuses on the development and application of small-scale models that describe in detail chemical, microphysical and biological processes in clouds.

Previous work includes
- the development of detailed CHEMICAL mechanisms of reactions occurring in cloud droplets. My early work was the development of the chemical aqueous phase radical mechanism (CAPRAM). In addition, I was one of the first researchers who suggested that in addition to sulfate, also organic aerosol may be formed in cloud droplets and in aqueous aerosol (aqSOA).
- the implementation and analysis of MICROPHYSICAL data and processes in cloud models. We showed that the representation of CCN properties can be largely simplified for most cases. In detailed model studies of ice microphysics, we explored the sensitivities and key parameters of ice nucleation in mixed-phase clouds.
