I am a stable isotope biogeochemist, studying carbonates secreted by terrestrial as well as marine and freshwater animals. My research interests lie within the reconstruction of past environments, and the study of ecological interactions by means of stable isotope and trace element analyses of biogenic carbonates.
The focus of my current reasearch lies on earthworm secreted calcite granules. I try to construct a new terrestrial palaeo-environment thermomenter and to quantify carbon sequestration potential of earthworms.
