Dr. Dirk Sachse
Funktion und Aufgaben:Senior Scientist
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.

SECCO Chile - The coupled vegetation, weathering, erosion, and sediment-export response to climate change unravelled from novel proxies in Chilean marine sediment (funding through a DFG grant within the EarthShape SPP) - collaboration with H. Wittmann (GFZ) and A. Bernhardt (FU Berlin). I am responsible for reconstructing vegetation and hydrology from marine and on-shore sediments using lipid biomarker C and H isotope ratios. With jointly supervised PhD student Néstor Eduardo Gaviria Lugo at GFZ.
