Currently, I am a PostDoc in the research group of Matthias Schwarz at the University of Leipzig. Until October 2022, I was a PostDoc in the research group of Max v. Renesse. In January 2021, I defended my thesis as a PhD assistant in the research group of Anton Thalmaier at the University of Luxembourg. My research is concerned with Stochastic Differential Geometry, i.e. the combination of stochastic analysis und differential geometry. As a relatively young and interdisciplinary subject this area uses stochastic methods in order to explore classical analytical problems on manifolds. The deep connection between the Laplacian as generator of Brownian motion seemlessly opens ways to study the whole manifold by virtue of the paths of this stochastic process. Moreover, stochastic methods can be used to solve problems where analytic methods may fail.From March 2017 to February 2020, I was the PhD represenative of the mathematics research unit in the Doctoral Programme Mathematics and Applications at the University of Luxembourg and created a little, responsive website covering all coordinates about our PhD seminar.

minflat Beamer Theme
The minflat theme is a Beamer theme in modern flat design, i.e. emphasising a minimal yet functional design, primarily designed for mathematical talks. You can choose between two colour schemes: a blue violet and a red purple variant. Corresponding colours used are green for the progress bar (and examples) and orange for alert elements. -
Tractatus logico-philosophicus - tractatus 2.0
The project tractatus 2.0 is an attempt to allow you to sort the paragraphs resp. its propositions flexible but relative to its priority which is scarcely possible in reality. The well-known visualisation as a hierarchic (tree) structure, as it is currently used, must be overcome, aiming at detaching every paragraph and being able to look at it individual. Accordingly, our aim is not to break structure of the Tractatus itself, but create you a platform to play and explore the overwhelming possibilities the paragraphs itself or in the variety of feasible options can be arranged and thus understood.
