Since April 2018 I am a PostDoc at the University of Hamburg. Initially in the working group of Prof. Dr. Michael Hinze, I changed to the group of Prof. Dr. Armin Iske in April 2019 and am also co-supervised by Prof. Dr. Ingenuin Gasser. My research interests are modeling, asymptotic analysis and simulation of partial differential equations describing thin films.

This Winter Term 2020/21, I teach virtual exercise classes in "Computer Tomography" at the University of Hamburg and "Differentialgleichungen I für Studierende der Ingenieurwissenschaften" at Hamburg University of Technology (TUHH).
