Research interests

I apply different geochemical tools such as major-, trace elements, radiogenic (Nd, Sr, Pb) and non-traditional stable (Zn, Mo, Se) isotope systems to investigate magmatic processes, surface recycling and mantle evolution on our planet over geological timescales. In detail, I study the short-term recycling of elements at currently active subduction zones as well as the long-term surface and crustal recycling from the compositions of the plume-influenced ocean island lavas. 

My second research interest is the interaction and effects of climate change and increasing human activities on the Earth surface environment. Specifically, I investigate trace element and isotope compositions of particles deposited onto archives such as lakes and ombrotrophic peat, which act as fingerprints of such processes.

My recent project funded by the Excellence Strategy of State of Baden Württemberg and University of Tübingen for early career postdocs aims at investigating the climate change and human impact controls on saline and fresh-water lakes of East Africa. These extremely vulnerable ecosystems have the potential to record the evolving interaction between climate, geology, hydrology, biological and human activity, and represent therefore an integrated witness of ancient and present environmental conditions in equatorial and sub-equatorial regions of our planet.  

Students interested in completing a BSc and MSc thesis within these projects are encouraged to contact me.
