Sandra Albrechtsen
I am a PostDoc at Leipzig University with James Davies in the discrete mathematics group led by Dan Král'. From 2021 to 2025, I was a PhD student at the University of Hamburg under the supervision of Reinhard Diestel.
I am interested in graph theory and, more broadly, combinatorics. My research focuses on structural graph theory, particularly coarse graph theory, graph-decompositions, tangles and infinite graphs.
When i am not doing math, I enjoy painting, gaming, reading and playing `The Gang' or `Tempel des Schreckens'.
