Forschungsinteressen
Ich beschäftige mich mit Algorithmen für diskrete und kontinuierliche Optimierungsprob-
leme und deren Anpassung für die Kallibrierung (Parameteroptimierung) und Bewertung
von Biogeochemischen Ozeanmodellen. Derzeit arbeite ich im EU-Projekt OceanICU “Un-
derstanding Ocean Carbon”.
