Forschungsinteresse
Mein Forschungsinteresse gilt der Paläoozeanographie mit Blick auf den Nordpazifik, die Ozeanzirkulation, die zeitliche und räumliche Änderung der biologischen Primärproduktion und des Klimas seit dem Miozän. Ich untersuche diese Veränderungen anhand von Mangankrusten und Sedimenten als Archive, und nutze hierbei die Verteilung von Spurenmetallen und die Isotopenzusammensetzung von Nd-, Ba-, Fe- und Cu.
