Teaching

For the following courses at RWTH Aachen University I had various responsibilities (creating exercise sheets, conducting exercise sessions, write lecture notes, etc.). The lectures were all at the Chair of Management Science headed by Britta Peis who was the main lecturer in all of those courses.

• Algorithmic Game Theory (for Economics) with Komal Muluk, Summer 2024
• Strategic Decisions in Networks, Markets, and Politics with Komal Muluk, Winter 2023/24
• Algorithmic Game Theory (for Computer Science) with Lennart Kauther, Summer 2023
• Einführung in Design und Analyse von Algorithmen, Summer 2022
• Scheduling, Summer 2020
• Einführung in Management Science, Winter 2019/20, Winter 2020/21, Winter 2021/22
• Highlights in Optimization (seminar), every term between Winter 2019/20 and Summer 2024

As a student at RWTH Aachen University, I also was a TA in the following courses given by the Chair of Logic and Theory of Discrete Systems headed by Martin Grohe and the Theoretical Computer Science group headed by Peter Rossmanith:

• Formale Systeme, Automaten, Prozesse, Summer 2014, Summer 2015, Summer 2016, Summer 2017
• Berechenbarkeit und Komplexitätstheorie, Winter 2015/16, Winter 2016/17
• Datenstrukturen und Algorithmen, Summer 2019
