I am a postdoctoral researcher working on air-sea interactions under the supervision of Cathy Hohenegger. As a member of the collaborative research center TRR 181 I am studying the interplay between atmospheric convection and near-surface meter-scale processes in the ocean. Prior to that I was working as a researcher in probability theory and mathematical statistics in the group of Jeannette Woerner at TU Dortmund.

Research

As postdoctoral researcher at MPI I am interested in understanding and quantifying interactions between diurnal warm layers in the tropical ocean and shallow convection. For this I mainly use the output of ICON simulations, but also observational data.

In Mathematics, my research interests lie in stochastic (partial) differential equations driven by fractional Brownian motion (or other Hermite processes) and applications in statistical inference. I am also interested in studying random fields on the sphere. In the majority of my works I use the Malliavin-Stein machinery for Gaussian processes, and I am fascinated by its various applications.

On the intersection of Mathematics and Geosciences my interests are in demonstrating theoretical results for processes that can be modelled involving randomness.
