Function and Responsibilities:

I am Labmanager in Section 4.6 - Geomorphology and responsible for the Organic Surface Geochemistry Lab (OSGL), the Sediment Lab (SedLab) and the Physical Experimental Lab (PhyLab). In addition to the general organization of our laboratories, my major tasks are analytical method development, documentation, quality assurance and the coordination of laboratory staff.

Research Interests:

My scientific interests are the interactions between atmosphere, biosphere and lithosphere, especially how changes in one system can trigger, weaken or amplify processes in another (i.e. hydroclimatic changes and erosion). My research activities are focused on the investigation of climate variability (on short and long-term time scales), their causes and effects on the regional hydrological cycle and ecosystem to improve our understanding of the underlaying key mechnisms.

In addition to water isotope analysis (d ²H, d ¹⁸O, d ¹⁷O) I mainly work with molecular fossils (biomarkers) as proxy for spatial and temporal changes in hydroclimatic and ecological conditions. Biomarker analysis in general (i.e. Alkenone, GDGT's) as well as the compound-specific analysis of stable hydrogen (d ²H) and carbon (d ¹³C) isotope ratios (i.e. n-alkanes, fatty acids, sterols) enables the detection of even small changes in atmospheric circulation systems, temperature and /or regional vegetation cover. The second major part of my research activity is covered by the development and testing of new analytical methods and proxies in biomarker applications and stable isotope analysis.
