Jonas Blessing

About me: My name is Jonas Blessing and I am currently a PostDoc at the Department of Mathematics and Statistics at the University of Konstanz. Prior to that, I was a PostDoc at ETH Zurich in the research group of Josef Teichmann. In September 2023 I completed my PhD at the University of Konstanz under the supervision of Michael Kupper. My PhD thesis has been awarded with the Airbus Research Grant Claude Dornier.

My reasearch interests are nonlinear semigroups, stochastic analysis and mathematical finance.
