Research interests
I am a postdoctoral researcher at the Max Planck Institute for Meteorology, interested in land-atmosphere interactions within storm-resolving Earth System Models. My research explores questions such as which soil moisture conditions—wet or dry—can trigger precipitation in these high-resolution models. Additionally, I’m interested in how the estimation of carbon stocks and fluxes in storm-resolving models differs from current understandings.
Beyond my core research, I enjoy…
We investigate the full methane cycle over timescales of millennia. Within the Palmod, we developed a full representation of the natural methane cycle in MPI-ESM: We consider wetlands, wildfires, termites and herbivores as methane sources, and also determine the soil and atmospheric sinks of methane, the latter together with the MPI for chemistry.
We have investigated methane from the LGM to a millennium into the future, leading to two superb publications.
Modelling the global methane…

I arrived at the Max Planck Institute in Hamburg by a roundabout way. Nature, our Earth, and the universe have always interested me. That's why I started studying physics, in order to understand what holds the world together at its core. Physics is magnificent: armed with a toolbox of mathematics, physicists look out into the world…

Research
Precipitation - and rain in particular - are important natural phenomena for human life on our planet. We have known for a long time that all water that evaporates from the Earth's surface will eventually return to the surface as precipitation. But which processes or characteristics of the Earth system determine how precipitation gets partitioned between land and ocean? Do fundamental physical laws such as water and energy balance equations constrain this partitioning? How do surface…
Research Interests
I am currently a PhD candidate in the DFG-funded research unit TERSANE II (Temperature related stresses as a unifying principle in ancient extinctions) with the NUC project. My research contributes to the reconstruction of the ocean carbon and nutrient cycles and their interactions with climate during the Permian-Triassic transition. In this context, I am particularly interested in using Earth System Models to bridge the timescales which were present during the…
My research focuses on using next-generation km-scale general circulation models to understand fundamental aspects of various atmospheric circulation systems — ranging from local thunderstorms up to global-scale wind systems. Km-scale models explicitly resolve, rather than parameterize, atmospheric convection and gravity waves, allowing for a much more detailed understanding of these processes and their role in different circulation systems. I’m particularly interested in using my scientific…
