Postdoctoral researcher at the ​German Research Centre for Geosciences (GFZ-Potsdam, Germany) working on understanding past abrupt climate change. Within Dr Sachse’s team, I study changes in aridity and precipitation patterns at the end of the last ice age (15.000 – 10.000 years ago) across the European continent using a novel dual biomarker approach involving hydrogen isotopes.

In general, I am fascinated by the interactions and feedbacks between the biosphere and the geosphere at different spatial and temporal scales in marine and terrestrial environments. The development of new tools such as those involving stable isotope measurements to investigate biogeochemical processes is fundamental to my research.

Visiting Prof. Rickaby’s group in Oxford, I also explore how vital effects on stable-isotope composition of organic molecules could be exploited in novel ways to track important marine biogeochemical processes.
