Research

Motivation and scope

I am Quaternary geologist / sedimentologist by training, with a broad range of interests. My research focus is the recent geological history of the Alpine realm in the widest sense. I investigate landscape modifications, sediment transport and depositional environments from the mountain range over the (especially northern) Alpine foreland to distal settings such as the Upper Rhine Graben. 

Current projects

• Investigating Early-Stage Quaternary Overdeepening in Oberschwaben, DE (as part of ICDP DOVE)
  07/2023 - 06/2026
  Deutsche Forschungsgemeinschaft (DFG) project no. 517980590
• Quaternary stratigraphy in the Upper Rhine Graben, DE/FR
  (05/2023 - 05/2024: palynological analyses funded by Wissenschaftliche Gesellschaft Freiburg)
• Quaternary stratigraphy in the Ossola Valley, IT (as part of ICDP DIVE)
  (05/2025: VERAcore seed grant for radiocarbon dating)
• Geotechnical properties of glacigenic sediments
