Born 1971 in Freiburg i.Br. (Germany), I studied Geology at the Eberhard-Karls University in Tübingen (Germany), the California State University in San Diego (USA), and the ETH Zürich (Switzerland), where I received my MSc in 1998 and my PhD in 2002. Between 2002 and 2004, I worked as a postdoc at the Department for Geosciences at Princeton University, first as a fellow of the German Research Foundation (DFG) and then as Research Associate. In 2004, I became Assistant Professor at the Department des Sciences de la Terre et de l'Atmosphère at the University of Québec in Montréal (Canada). Since 2007, I am Professor for Biogeochemistry at the Department for Environmental Science and Head of the Group "Aquatic and Stable Isotope Biogeochemistry". Since 2014 I serve as Dean of Research at the Faculty of Science at the University of Basel.


Research Interest

I am interested in the research fields of Aquatic Biogeochemistry, Stable Isotope Biogeochemistry, organic geochemistry, microbial ecology and (paleo-)limnology.

Current research activities include the application of isotope and organic geochemical methods to study N and C cycling reactions and trace gas production (N2O, CH4) in freshwater and marine environments. I am also interested in research related to the preservation and degradation of organic matter and associated isotope effects. The spatial scale of my research extends from enzyme-level biogeochemistry to ocean-scale circulation, with implications for the understanding of intracellular metabolic processes, as well as for global element cycles. 

My record shows a long history of work in Lake Lugano in Southern Switzerland. Lake Lugano is an excellent model system to study biological N and C transformations and their associated isotope fractionation, and to study the environmental and biological controls on the production and consumption of climate-relevant gases in lacustrine environments.
