Mein Hauptinteresse gilt der Entwicklung der afrikanischen Vegetation in Zusammenhang mit der Klimavariabilität.
Dafür (unter)suche ich Pollen und Sporen in marinen Sedimenten.
Viele meiner Arbeiten beschäftigen sich mit dem spätpleistozänen Glazial-Interglazialzyklus, aber einige auch mit neogenen Entwicklungen.

Sehen Sie bitte weiter auf dem englischsprachigen Teil der Website.

Main topic of my research is the development of the African vegetation in association with climatic change.
To this end, I study pollen and spores from marine cores and sediment samples.
Much of my work covers the Late Pleistocene glacial-interglacial cycle, but I am also interested in the older parts of the Neogene.
