Research Interest

I am a stratigrapher and micropaleontologist. My main interests are: (1) Precise dating, large-scale correlations and improvement of the Geologic Time Scale, (2) Climatic and biotic events in a Greenhouse World, (3) Evolution of marine life. As a micropaleontologist, I am a specialist of calcareous nannofossils. As a stratigrapher, I am specialized in cyclostratigraphy and carbon-isotope stratigraphy. My focus intervals are the Jurassic, Cretaceous, the Paleogene and the Quaternary.
