Diploma in Geology/Palaeontology (Lud-wig-Maximilian-Universität München / DE)

PhD in Cenozoic Micropalaeontology and Stratigraphy (Université de Fribourg / CH)


I am working in close collaboration with my fellow Responsable d’étude Gaëtan Rauber on the intriguingly variable Cainozoic sedimentary system (s.l. called “Jura Molasse”).

My focus is on the determination and interpretation of the diverse micropalaeontological as-semblages.

I am also contributing to the collection management of the Cainozoic fossil material.
