PhD Position in Environmental Chemistry / Stable Isotope Biogeochemistry

100% / expected start date is at the earliest conveniece

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.

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 at the earliest convenience.

Your assignments

The PhD project will involve extensive laboratory work with the use of stable isotope mass spectrometry methods (IRMS, GC-IRMS). The aim of the project is to systematically investigate stable isotope fractionation of molecular oxygen during microbial and abiotic oxygen consumption processes relevant for aquatic environments. The reaction-specific isotope fractionation pattern determined in laboratory experiments will ultimately help to improve the use of oxygen stable isotope analysis as a tool to study redox reactions of natural or anthropogenic organic compounds at different scales. 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.

Interested candidates should submit a letter stating their motivation, experience and skills, a CV, and contact details of at least two references. We accept only online applications
