As a scientific coordinator of the German Center for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig at the Friedrich Schiller University Jena, I am strongly involved in projects addressing microbial biodiversity in terrestrial environments such as in the framework of the iDiv platform CRC 1076 AquaDiva (subsurface/aquifer biodiversity). Using next generation sequencing approaches, we aim to get more insight into the functional diversity of prokaryotic and eukaryotic microorganisms in aquifers, and to what extent they are influenced by microorganisms originating from the soils of the respective groundwater recharge areas.

In addition, I am interested in different aspects of the microbial ecology of the nitrogen cycle. Within the subproject B05 of the CRC 1076 AquaDiva, we investigate the origin and fate of nitrate in the Critical Zone by following nitrogen cycling microbes and their activities from forest tree canopies via throughfall and seepage down to the groundwater (PhD project Markus Krüger). Along with that, we also study distribution patterns of microorganisms involved in nitrification and their activities in soils under different land use (master project Florian Deckner). Using activity assays and molecular methods such as qPCR and next generation sequencing, we want to gain more insight into which key environmental factors determine the abundance and community composition of these microbial groups and the corresponding nitrogen turnover processes in soils and aquifers.
