Currently, I am a PhD Student and research assistant in the Theoretical Computer Science group.

Teaching

This summer I organize a seminar on Online Algorithms.

In the past, I worked in various ways for the following courses:

In 2022 and 2023 I led the RWTH-team at the International Mathematics Competition. Furthermore, organized the Competitive Programming Contest at RWTH Aachen.

In particular, I am proud of our yearly lab course Algorithmic Battle, which I have hosting in recent years.
Its unique teaching concept allows students to find out themselves what makes a problem hard in various settings, and furthermore lets participants experience the importance of rigorous testing when developing code. We obtained funding from a Freiraum Grant from Stiftung Innovation in der Hochschullehre and a grant within the ICON ENHANCE Call 2025 for the further development of our lab.

Supervised Theses

The following thesis projects were completed already:

Publications and Talks

In addition, you might have seen my talks at the Workshop on Recent Trends in Online Algorithms (ICALP 2023), the Dutch Day on Optimization 2023, the Seminar on Graphs and Optimization at LaBRI, or here in Aachen.

Scholarships and Awards

Studies

Before starting in the Theory Group, I studied mathematics with minors in economics and computer science at RWTH Aachen University. I obtained my master's degree with honors in December 2020.
