What I am doing:
I am currently a PhD student of the Mathematics Münster Graduate School at Universität Münster under the supervision of Prof. Dr. Linus Kramer.Research interests:
I am interested in buildings (of spherical type), incidence geometry, group theory and combinatorics.Preprints, eprints, publications and other writings:

Poster:
I created a poster for the Buildings 2024 conference, which is a comic that roughly summarizes what I did in my first 2 years of my PhD. You can find the pdf here.Teaching:
 Teaching assistant for Foundations in Analysis, Topology and Geometry (SS24)
 Tutor for Analysis I (WS19/20)
 Tutor for Linear Algebra II (SS19)
 Tutor for Mathematics For Physicists III (WS16/17)
Miscellaneous:
 If you are interested in using GitHub for writing papers together or if you are interested to know, why this could make sense for you, then I have this little pdf that gives some reasons and can help to set it up: Get onto GitHub.
 I was organizer of the Buildings 2024 conference.
 I was organizer of the seminar (Tea Seminar) of the research group Geometry, Topology and Group Theory at the university of Münster for the summer term 2024.
 I get funding through the Dissertation Plus Scholarship of the ClaussenSimonStiftung and the Diversity Support Fellowship of the Cluster of Excellence Mathematics Münster.
 I am a member of the Fachgruppe Gender, Diversity and Sustainability in Mathematics of the German Mathematical Society since the 23rd of June 2023 and contact person for questions regarding trans identity and neurodiversity.
 I am a math ambassador of the Stiftung Rechnen since 2017.
