I have a general interest in atmospheric dynamics and aerosol in the Earth system. Motivated by the uncertainty in aerosol effects on climate, I am particularly interested in model simulations of meteorological processes that are important for aerosol-climate effects. 

Desert-dust aerosol

In previous work, I have focused on meteorological processes driving desert-dust emission in North Africa. Most of the Earth's dust aerosol is emitted in this part of the world, but models show large diversity in emission amounts. I have developed benchmark climatologies for the relative importance of different dust-emitting processes, such as the nocturnal low-level jet mechanism, mobile cyclones and the post-frontal strengthening of trade winds. Estimates of dust emission amounts associated with these processes have been helpful in evaluating weather and climate models at a process level. Find out more in my publications.

Anthropogenic aerosol

At MPI-M, I follow my interest in the atmospheric response to aerosol perturbations. I use models of different complexity and observations to help advancing our understanding of the role of aerosol in the Earth system. I am developing the parameterisation Initiates file downloadMACv2.0-SP for optical properties of anthropogenic aerosol as a contribution to the “Radiative Forcing Model Inter-comparison Project” (RFMIP) under the umbrella of CMIP6. The code of MACv2-SP is available as supplement of our GMD article and input4MIPs. Currently, the temporal scaling is for the historical time period. The future scenarios for MACv2-SP based on CMIP6 emission data are available in the supplement of our recent article. 

Ocean expeditions

I further work on research vessels to collect atmospheric reference data over oceans. Here, I focus on aerosol and innovative cloud observations. I wrote blogs on the research and life aboard RV Polarstern and during my expedition with RV Maria S. Merian, and participated in other outreach projects for inspiring the next generation of scientists.


My experience in university teaching include supervising bachelor and master students, preparing and leading classes in climatology, tutorials in intermediate and advanced mathematics as well as assisting in practical classes on climate change and fundamental knowledge in meteorology.
