In the PhD college FATE we want to improve our understanding of the fate and effects of antibiotics and antibiotic resistance along the pathways from environmental source to sink compartments.

I am working in the FATE project III - Surface waters - since June 2020, studying the Holtemme river in the Harz mountain region in central Germany. Antibiotics in surface waters are an immediate concern primarily due to the spread of antibiotic resistant bacteria. Little is known, however, about how antibiotics are affecting microbial functions and the ecology of natural microbial communities. An equally important aspect of the environmental dimension is the fate of antibiotics in the aquatic environment. In this context, this PhD project is using stable isotope labeling combined with molecular biology and single-cell approaches to address these knowledge gaps in field studies and lab-scale experiments.
