Research Interests

As a ecophysiologist and biogeochemist I am interested how carbon, water and nutrients move through a plant, how environmental changes drive plant physiological and metabolic responses, and how information about this processes can be derived from the stable isotopic composition of plant material. I like to combine experimental plant studies with research tools from various disciplines such as compound-specific isotope analyses (LC- & GC-IRMS, IRIS & CRDS), plant physiological measurements (gas-exchange & leaf traits), plant molecular biology (plant mutants), and biochemical approaches (enzyme activities, compound concentrations).

Recently, I lead a SNF Ambizione research project (TreeCarbo) focusing on carbon, oxygen, and hydrogen isotopic composition of carbohydrates (sugars, starch, tree-rings) to better understand how information about plant functions and climatic conditions are laid down into tree-ring archives. Besides, I develop a new compound-specific nitrogen isotope method to study wood decomposer food webs (IsoWeb).
