Seit November 2016 bin ich Post-Doc in der Arbeitsgruppe von Prof. Dr. A. Iske.
Ich bin assoziiertes Mitglied des Graduiretenkollegs RTG 2583: "Modeling, Simulation and Optimization with Fluid Dynamic Applications" und organisiere das Lothar Collatz Seminar.
Von November 2016 bis Dezember 2020 war ich Teil des TRR Projekts TRR 181 "Energy Transfers in Atmosphere and Ocean". Zuvor, bis Oktober 2016, war ich Post-Doc an der Universiät Trento (Italien).
