I am a PhD candidate in the Applied Mathematics Group led by Gabriele Steidl at TU Berlin working on Wasserstein gradient flows, regularized f-divergences and regularized optimal transport.

My master's thesis "Wasserstein gradient flows with an eye towards positive matrix measures" (2023) is about sparse convex optimisation in spaces of measures and my bachelor's thesis is entitled "Atomic Norm Minimization for Superresolution" (2021).

When I am not doing maths, you can find me visiting the opera or the concert hall or playing badminton and table tennis.

Teaching at Technische Universität Berlin

During the school year 2022/23 I was a tutor at the Mathematische Schülergesellschaft "Leonhard Euler", where I, on a weekly basis, went through stimulating maths puzzles with interested seventh-graders.

Unofficial lecture notes & flashcards

Below you can find some lecture notes I wrote for courses I attended at TU Berlin in descending order by quality. I am satisfied with the top eight, read the rest at your own risk. If you find any errors or are perhaps an instructor discontented with the material shared here, please contact me at lastname at math.tu-berlin.de.

To help me study for the exams, I have created texed flashcards: [Approximation theory], [Functional Analysis II], [Topology I]. Beware that they might be incomplete and will probably contain errors. You can contact me at the above email adress if you want the corresponding .tex files.

To help me study for the exams, I have created LaTeX flashcards, some for lectures mentioned above, and also these: Approximation Theory, Functional Analysis II, Topology.
