About me
I am an assistant professor at University of Leipzig.
Prior to moving to Leipzig, I was a postdoctoral researcher at University of Kassel in the Discrete Mathematics group led by Torsten Mütze. From October 2025 to March 2026, I was at Charles University in Prague, Czech Republic, to work on my project "Extending Automorphisms of Structures: Interactions of group theory and model theory", funded by the German Academic Exchange Service (DAAD). My advisor in Prague was Jan Hubicka. From 2022 to 2024, I was a postdoctoral researcher in the group of Pascal Schweitzer at TU Darmstadt. From 2019 to 2022, I was a PhD student of Burkhard Külshammer at Friedrich Schiller University Jena.
I am interested in research topics at the intersection of group theory and combinatorics. During my PhD, I worked in representation theory of finite groups and symmetric algebras. As a postdoctoral researcher, I became interested in topics in combinatorics and algebraic graph theory. I also work on projects in theoretical computer science.
Some news- The entire IT of Leipzig University is currently offline, so I cannot be reached by my institutional mail address. Please contact me via sbrenner[at]mathematik.uni-kassel.de or sofia[at]kam.mff.cuni.cz.
- I organize two workshops in Oberwolfach in 2028: one on symmetry breaking (with M. Anders, C. Hojny, and M. Pfetsch) and one on structural Ramsey theory (with J. Hubicka, S. Todorcevic, and A. Zucker).
- Constant delay Gray code enumeration of ideals and antichains in posets (with J. Fink) was accepted for SODA 2027.
