Sebastian Hensel
Postdoc in Mathematics (Leipzig University)
Welcome to my webpage. As of October 2025, I am a postdoc
in the group of Bernd Kirchheim at Leipzig University.
Previously, I was a Hausdorff Postdoc at the
Hausdorff Center for Mathematics,
University of Bonn, including a parental leave from August 2023 to September 2025. 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.
