About Me

Since 2020 I'm a PhD Student in the Discrete Geometry and Topological Combinatorics Group at Freie Universität Berlin. My advisor is 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. I did a Bachelor of Science in Natural Science in the Society of Information (original in German: "Naturwissenschaften in der Informationsgesellschaft") also at TU Berlin and spend a year at Universidad Catolica de Temuco, Chile. I also completed a study program about gender and diversity aspects in STEM (Zertifikat I, information in German here). During high school, I spend one year in Cuenca, Ecuador.
