Open Positions

Research Scientist in Isotope Biogeochemistry (6 years)

The University of Basel invites applications for a Research Scientist position (non-tenure track) in the Aquatic and Stable Isotope Biogeochemistry working group of the Department of Environmental Sciences (Prof. Dr. M. Lehmann). We are seeking highly motivated candidates, preferably with at least two years of post-doctoral experience in stable isotope geochemistry and biogeochemical cycling of elements in aquatic systems (marine and freshwater). Potential candidates with expertise in combining isotopic (natural abundance, isotope enrichment, and/or compound-specific/biomarker) geochemical, and molecular approaches to study element cycles in pelagic and/or benthic environments on different spatial/temporal scales, and with interest to integrate experimental and field research are particularly encouraged to apply. A background in nitrogen isotope biogeochemistry (e.g., NOx, N2O) is not a requirement, but will be an asset. The successful candidate is expected to initiate his/her own research projects, as well as to join ongoing and planned multidisciplinary projects in the broader fields of stable isotope biogeochemistry. He/she is also expected to contribute to the teaching activities at the undergraduate and graduate levels.

We offer a positive working environment with high-quality research facilities (e.g., four IRMS, two QMS, three GC peripheries) and a competitive salary. The appointment will be for two years, with a possible extension up to six years, starting in November 2017 or later. A PhD degree is required.

Candidates should submit a letter of application, statement of research and teaching interests, a curriculum vitae including a list of publications, and addresses of at least two referees to Prof. Dr. Moritz Lehmann, Department of Environmental Sciences, University of Basel, Bernoullistr. 30, CH-4056 Basel, Switzerland. E-mail applications are preferred.

For further information please contact Prof. Lehmann (moritz.lehmann-at-unibas.ch). Review of applications will begin August 15, 2017. Applications will be considered until the position is filled.

2-3 Year Postdoc position in nitrogen isotope biogeochemistry


The Aquatic and Isotope Biogeochemistry Group at the University of Basel invites applications for a Postdoc position in the fields of Nitrogen Isotope Biogeochemistry. We are seeking a highly motivated candidate with experience in stable isotope biogeochemistry in aquatic environments who demonstrates interest in geochemical and (micro-) biological processes also in engineered (wastewater) systems. An expertise in nitrogen isotope/mass-spectrometric techniques and bioreactor work will be an asset. The successful candidate will be part of an SNF-funded Sinergia project (three postdocs and one PhD), which aims at testing isotopic and molecular tools to understand links between biogeochemical pathways, the performance of microbial communities, and environmental conditions during autotrophic nitrogen removal in mixed nitritation-anammox systems. The postdoctoral project will make use of an established set-up of enriched and mixed-culture nitritation-anammox reactors at the laboratory and pilot scale, focusing on the isotope effects of anaerobic nitrate formation by anammox, and testing the potential of nitrate/nitrite nitrogen and oxygen isotope measurements to diagnose biochemical reactions in waste water treatment systems employing partial nitrification and anammox. The planned experiments are expected to advance our understanding of the environmental controls on anammox and its isotopic fingerprints also in natural environments.


The project will be conducted in close collaboration with the Eawag in Dübendorf and Kastanienbaum (Dr. A. Joss, Dr. H. Bürgmann), and with the EMPA in Dübendorf (Dr. J. Mohn). The full-time appointment will be for two years, with a possible extension for another year. Start date: 1. October 2017 or later. A PhD degree is required. Candidates should submit a letter of application, a CV including a list of publications, and addresses of at least two referees to Prof. Dr. Moritz Lehmann (moritz.lehmann-at-unibas.ch), University of Basel.

For further information please contact Prof. M. Lehmann. Review of applications will begin May 1, 2017 and will continue until the position is filled.
