Title of the PhD Thesis
Population-based assessment of gut microbiota-host interactions

The gut associated microbial ecosystem – intestinal microbiome – has an important influence on human health. We are focussing on the composition of the gut microbiome and its impact on different life stages and health statuses. Furthermore we are trying to find diet-associated pattern. Therefore, stool samples from a state-of the art population-based prospective cohort – KORA – are analysed via high-throughput sequencing.
