Seit November 2016 bin ich Post-Doc in der Arbeitsgruppe von Prof. Dr. A. Iske's. Im TRR Projekt TRR 181 "Energy Transfers in Atmosphere and Ocean" arbeite ich in Teilprojekt M5: "Reducing spurious diapycnal mixing in ocean models" an der Entwicklung und Analyse von Advektionsmethoden hoher Ordnung.

Zuvor, bis Oktober 2016, war ich Post-Doc an der Universiät Trento (Italien).
