Eawag, the Swiss Federal Institute of Aquatic Science and Technology, is an internationally networked aquatic research institute within the ETH Domain (Swiss Federal Institutes of Technology). Eawag conducts research, education and expert consulting to achieve the dual goals of meeting direct human needs for water and maintaining the function and integrity of aquatic ecosystems.
PhD student in Environmental (Bio)Chemistry
The Department of Environmental Chemistry is offering a position for a
The position is part of a project funded by the Swiss National Science Foundation (SNF) aiming to assess the dynamics of microbial metabolism in soil and water upon human-induced environmental change. Questions on ecosystem functioning will be approached through a wholistic evaluation of microbial phosphorus metabolism using stable isotope-based evidence as proxy for the study of phosphoryl transfer reactions in aerobic heterotrophic bacteria.

This study will be carried out in an interdisciplinary team working at the intersection of environmental sys-tem sciences and biochemistry.

This work will focus on the elucidation of intracellular phosphorus metabolism through stable isotope anal-ysis of phosphate and organophosphorus compounds. The student will isolate, purify, and characterize the relevant enzymes and study the expression of oxygen isotope effects in metabolic reactions respon-sible for consumption, transfer, and release of phosphate during microbial activity. The outcome of this work will feed into quantitative metabolic models for the interpretation of the observable isotopic finger-prints of phosphate.

We seek applications from individuals with a strong interest in developing expertise in biochemistry and molecular/chemical biology related to environmental phenomena of phosphorus cycling. Potential candi-dates hold a MSc degree in a relevant discipline of chemical, biological, or environmental sciences. We expect excellent writing and communication skills in English. Creativity and independent thinking as well as the ability to work in teams will be critical requirements for joining this project. The successful appli-cant is expected to start this position between September and October 2022. The position will be limited to four years.

The successful applicant will join the Environmental Chemistry Department at Eawag, and be part of a collaborative project carried out the Group of Plant Nutrition at ETH Zürich,

This position also comes with the opportunity to work with researchers from ETH Zürich and the Universi-ty of Bern in an interdisciplinary working environment and in state-of-the-art laboratories. The successful candidate will be enrolled as PhD student at ETH Zürich and is expected to fulfil its admission require-ments,
