Zur Person

Funktion und Aufgaben:

Senior Scientist 
Head of the Organic Surface Geochemistry Lab at Section 5.1
Link to my publication record at  Google Scholar and my  Researcher ID

Wissenschaftliche Interessen:

My research is aimed at understanding the variability of the hydrological cycle on different timescales (101 to 106  years), as the basis of life, human societies, ecosystems as well as a pacemaker of the biogeochemical cycles, such as the carbon cycle.
