About Me

Since 2020 I'm a PhD Student in the Discrete Geometry and Topological Combinatorics Group at Freie Universität Berlin working with Matthias Beck. I am also a student of the Berlin Mathematical School.

Before that I did my masters in mathematics at the Technische Universität Berlin and spent two semesters at the Charles University in Prague, Czech Republic. My master thesis advisor was Stefan Felsner. Before that I did a Bachelor of Science in Natural Science in the Society of Information (original in German: "Naturwissenschaften in der Informationsgesellschaft") at TU Berlin and spend a year at Universidad Catolica de Temuco, Chile. During high school, I also spend a year in Cuenca, Ecuador.
