Aufgaben/ Forschungsgebiet:

Ich beschäftige mich mit Algorithmen für diskrete und kontinuierliche Optimierungsprobleme sowie deren Parallelisierung. Zur Zeit arbeite ich in den Forschungsplattformen des Exzellenzclusters 'The Future Ocean'. Mein aktueller Forschungsgegenstand ist die Bewertung von Biogeochemischen Ozeanmodellen mittels Parameteroptimierung (Modellkallibrierung) und zugehörigen Gütegarantien.
