Funktion und Aufgaben:

Senior Scientist 

Wissenschaftliche Interessen:

My research is aimed at understanding the variability of biogeochemical cycles over different timescales (10¹ to 10⁶  years), as the basis of life, human societies and ecosystems.

In particluar I am interested in the mechansims and consequences of short-term changes to the hydrological cycle, and the influence of surface processes (erosion, riverine transport, mass wasting) and tectonics (mountain range uplfit, earthquakes) on the short-term and long-term development of the carbon cycle.I apply and develop organic geochemical methods and use molecular and isotopic information to detect changes in these cycles and quantify fluxes.
