Sabrina is an Assistant Professor of Mathematics and a member of the Topology and Dynamics and Analysis research groups. She is interested in geometrically characterising highly irregular objects as well as in the question which geometric features one can hear when listening to the sound of a fractal drum. Her research lies in the interim of analysis, geometry and stochastics.

Qualifications

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

Biography

Sabrina studied at Georg-August-University Göttingen (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 Lübeck (Germany) and Institut Mittag-Leffler (Sweden). Before joining the University of Birmingham she was a temporary Professor of Mathematics at Georg-August-University Göttingen (Germany).
