100%, Zurich, fixed-term

As the global population expands, the demand for food rises steadily. Meeting these needs in a sustainable manner remains one of the greatest challenges of our time. It is becoming clear that recycling human wastes can provide effective fertilizers for enhancing soil fertility and crop production, soil amendments for increasing carbon sequestration, and a means for improving public sanitation and health. However, the potential health risks connected to these practices are still debated, especially since very little is known regarding how antibiotics potentially contained in these fertilizers impact the soil-microbial-plant nexus.


Job description


This two-year postdoctoral position will be a key component of the SNF Prima project “Understanding the impacts of antibiotics from human excreta derived fertilizers on the soil-microbial-plant nexus” awarded to Dr. Gina Garland. The main goals of the project will be to determine what types and quantities of antibiotics are contained in currently utilized human waste-based fertilizers across Africa, how soil physicochemical properties influence sorption and degradation of these antibiotics once applied, and how this in turn affects microbial functioning and uptake of antibiotics by crops. Within this project framework, the postdoctoral researcher will optimize a multi-residue extraction method to characterize and quantify antibiotics and metabolites in soils, plants, and fertilizers by using pressurized liquid extraction (PLE) and liquid chromatography coupled to mass spectrometry (LC-MS/MS). Additionally, he or she will lead a sorption study assessing the capacity of different antibiotics to sorb to soils with contrasting physicochemical properties, and also participate in a large scale greenhouse trial, assessing the fate and degradation of antibiotics contained in the recycled fertilizers during the growth of two model crops. It is expected that the results from these activities will be disseminated as scientific publications and presentations at conferences. The postdoctoral researcher will be supervised by Dr. Gina Garland, who is based in the Soil Resources group of Dr. Sebastian Doetterl (?url=www.soilres.ethz.ch&module=jobs&id=51985" target="_blank" rel="nofollow">www.soilres.ethz.ch). The experimental work will be conducted within the Soil Resources group at ETH and the analytical work will be conducted in the laboratory of Dr. Thomas Bucheli of the Environmental Analytics Group at Agroscope in collaboration with Dr. Christa McArdell of the Department of Environmental Chemistry at Eawag .

We are an innovative, interdisciplinary research team with well equipped working places and offer the opportunity to supervise master students in support of the research program. We are committed to promoting equal opportunities for women and men and to support the compatibility of family and work.


Your profile


We are looking for a highly motivated and team-oriented post-doctoral researcher with a doctoral degree in environmental or analytical chemistry or similar. A solid background in environmental organic trace analysis using LC-MS/MS is needed, and preferably knowledge on the analysis of solid environmental matrices and soil chemistry. In addition, a general interest in interdisciplinary research, sustainable agroecosystems and alternative management practices is preferred. We are looking for a creative individual with strong communication skills and excellent time management abilities. Candidates are expected to have excellent academic records and be fluent in written and spoken English.
