Sabrina Kombrink is a lecturer of Mathematics and a member of the Topology and Dynamics Research Group. She is interested in geometrically characterising highly irregular objects as well as in the question if one can hear the shape of a fractal drum.

Her research lies in the interim of Analysis, Geometry and Stochastics.


  • Dr. rer. nat. (PhD) in Mathematics, University of Bremen, Germany
  • Dipl. Math. (MSc) in Mathematics and Business, Georg-August-University, Goettingen, Germany


Sabrina studied at Georg-August-University Goettingen (Germany) and the University of Warwick (UK). She received her PhD (Dr.rer.nat.) from the University of Bremen (Germany) for which she was awarded the ‘Bremer Studienpreis’.

Sabrina held post-doc positions at the University of Bremen (Germany), the University of Luebeck (Germany) and Institut Mittag-Leffler (Sweden). Before joining the University of Birmingham she was a temporary professor of Mathematics at Georg-August-University Goettingen (Germany).
