Christina Kaiser investigated the mechanisms behind the Rhizosphere Priming Effect, i.e. the effect of the release of labile carbon and nitrogen by plant roots on microbial decomposition of soil organic matter. She developed a model which links carbon and nitrogen input by plants to microbial community composition and function in a spatially structured soil environment, and analyses how cooperation between microbial functional groups may lead to their coexistence and the emerging of the priming effect.
Kaiser received her PhD in Ecology (2010) from the University of Vienna.
