Postdoctoral Position in Aquatic Biogeochemistry & Remote Sensing

About the role

The Aquatic and Isotope Biogeochemistry Group at the University of Basel seeks a postdoctoral researcher for a two‑year project investigating algal production, organic matter export, and microbial nitrogen cycling in lakes, with a focus on nitrous oxide emissions and climate change impacts.

Key responsibilities

• Lead and coordinate seasonal lake sampling campaigns, including water‑column sampling, environmental profiling, and sediment trap deployment.
• Design and perform stable isotope tracer incubations to quantify nitrification, N₂O production, and related nitrogen transformations.
• Conduct laboratory analyses of nutrients, dissolved gases, and organic matter using established facilities.
• Integrate field and experimental data with satellite observations to link surface productivity, organic matter export, and N₂O production.
• Collaborate on data synthesis and biogeochemical modelling with partners at Eawag.

Required profile

• PhD in biogeochemistry, environmental sciences, limnology, aquatic microbial ecology, or a related field, completed by the start date.
• Experience in aquatic fieldwork and laboratory research, preferably involving nutrient cycling or greenhouse‑gas measurements.
• Ability to organise regular field campaigns, work independently, and collaborate effectively.
• Strong English communication and scientific writing skills; German is a plus.

Required skills

• Stable isotope tracer techniques.
• Satellite remote sensing and environmental data analysis.
• Lake sampling methods and water‑column profiling.
• Laboratory analysis of nutrients, dissolved gases, and organic matter.

What we offer

• Engaging postdoctoral position in an international, collaborative research environment.
• Access to lake sampling infrastructure, advanced analytical and stable isotope facilities, and computational resources.
• Opportunity to develop an interdisciplinary research profile spanning aquatic nitrogen cycling, greenhouse‑gas production, and remote sensing.
• Employment at 80‑100% FTE for two years, with salary and benefits according to University of Basel regulations.
