As a terrestrial ecosystem ecologist my research focuses on the linkage between plant and microbial functioning and ecosystem processes, i.e. on the role of plants and soil microbes and their interaction in controlling ecosystem processes. My work centers on grasslands and forests in the tropical and temperate biome.
During the last years I specifically focused on
(i) stable isotope fractionation in plants, microorganisms and ecosystems as integrator of physical and biological processes,
(ii) nitrogen/phosphorus nutrition of plants and microorganisms,
(iii) nutrient cycling in tropical and temperate ecosystems,
(iv) stoichiometric relationships in plants, microorganisms and the environment, and
(v) how global change affects plant – soil – microbe relations.
