Sebastian Hensel
Hausdorff Postdoc (Hausdorff Center for Mathematics, University of Bonn)

Welcome to my webpage. As of September 2021, I am a Hausdorff Postdoc at the Hausdorff Center for Mathematics, University of Bonn. I obtained my PhD under the supervision of Prof. Julian Fischer at the Institute of Science and Technology Austria (IST Austria). My main field of research is the mathematical theory of partial differential equations.
