Offer Description
The research groups „Groundwater-Surface Water Interactions“ and „Organic Contaminants“ in the Department of Ecohydrology and Biogeochemistry at IGB offer a PhD position to begin on 01 January 2027. This is a DFG-funded research project based in Berlin-Friedrichshagen.
The aim of this PhD position is to determine the role of reducing conditions and oxidoreductases for the attenuation and transformation of trace organic compounds (TrOCs), including pharmaceuticals and iodinated X-ray contrast media (ICM). Field experiments will be conducted in an urban river (River Erpe in Berlin) to elucidate the transformation of TrOCs and ICMs in the upper river bed, also known as the hyporheic zone, along pre-defined flow paths. A particular focus will be to determine the impact of oxidoreductases, seasonal fluctuations, and temporary, climate-induced intermittent river drying on TrOC and ICM transformation. Moreover, TrOC transformation will be investigated in an adjacent alluvial aquifer, which is used for drinking water production. The research will combine field sampling at River Erpe, laboratory sample preparation and chemical analytics, as well as data evaluation and paper writing.
We seek a dynamic scientist who is highly motivated to conduct a PhD in an inspiring research environment at IGB. IGB provides an attractive working environment and has excellent equipment, technical support, and provides a PhD programme for PhD candidates. The project will be conducted in close collaboration with Technische Universität (TU) Berlin with Dr. Anke Putschew and a PhD candidate at TU Berlin focusing on complementary laboratory experiments to elucidate the role of oxidoreductases on TrOC and ICM transformations under reducing conditions. The successful candidate should be willing to work in close collaboration with the TU Berlin PhD student to integrate results.
Your tasks
- Field work and sampling at River Erpe
- Laboratory sample preparation and analysis of water quality parameters
- Chemical analytics of trace organic contaminants with LC-MS/MS
- Data analyses and interpretation
- Writing of manuscripts for publication of scientific results in international peer-reviewed journals
