PhD Position in Environmental Chemistry / Stable Isotope Biogeochemistry

100% Start: 1 January 2020

The Stable Isotope and Aquatic Biogeochemistry Research Group at the Department of Environmental Sciences, University of Basel ( invites applications for a PhD position as part of a project investigating stable isotope fractionation of molecular oxygen during enzymatic and abiotic redox reactions relevant to aquatic biogeochemistry and pollutant dynamics.

Your position

The PhD project will involve extensive laboratory work with the use of stable isotope mass spectrometry methods (IRMS, GC-IRMS) to determine reaction-specific isotope fractionation during oxygen consumption experiments, which will be used to improve mechanistic understanding of the magnitude and variability of oxygen stable isotope fractionation and evaluate the potential of oxygen isotope analysis as a tool to study redox reactions of natural or anthropogenic organic compounds.

Your profile

We are looking for a highly motivated candidate with a master's degree in environmental sciences, geosciences, chemistry, biology, or a related discipline. Candidates are expected to have a solid background and interest in environmental chemistry, isotope geochemistry, and pollutant dynamics. Ability to work in an interdisciplinary team and good communication skills including fluency in English are essential.

We offer you

The PhD project will be part of a research project funded for 4 years by the Swiss National Science Foundation. We offer an international, multidisciplinary work environment and excellent research infrastructure. Compensation will be according to the guidelines of the Swiss National Science Foundation ( Expected start date is 1 January 2020 or at the earliest convenience.

Application / Contact

Interested candidates should submit a letter stating their motivation, experience and skills, a CV, and contact details of at least two references as a single PDF file to Dr. Sarah Pati (

Closing date: 18 November 2019
