About this position
Eawag’s Department of Fish Ecology and Evolution is seeking a postdoctoral researcher to investigate fish migration and life history variation in anadromous Arctic charr.
The project examines how glacial inputs shape fjord environments and how these environmental differences influence the ecology, movement patterns, foraging, phenotypic divergence, and local distinctiveness of Arctic charr populations. The research will compare populations using glacial-fed and tundra streams, fjords influenced by marine-terminating or land-terminating glaciers, and non-glacially influenced fjord habitats.
The study spans a local and latitudinal climate gradient in Greenland, extending approximately 1,500 km along the West Coast. The postdoctoral researcher will focus on life history variation among anadromous charr populations and will primarily use otolith microchemistry. The project also provides scope for the researcher to develop and contribute their own ideas concerning fish migration ecology, evolution, aquatic ecosystems, and climate-driven environmental change.
The postdoc will work with a dedicated PhD student and collaborate closely with early-career researchers studying adaptive radiation of Arctic charr in post-glacial lakes. The research is supported by existing field equipment, laboratory facilities, extensive Greenland field experience, and a research environment within the Center for Ecology, Evolution and Biogeochemistry in Kastanienbaum, Lucerne. CEEB brings together aquatic ecology, evolution, biogeochemistry, and ecosystem research at the shores of Lake Lucerne.
Fieldwork in Northwestern Greenland is planned for summer 2027, alongside analyses of fish life histories, fjord environments, trophic ecology, and population divergence across environmental gradients.
Funding details
The project is funded by the Swiss National Science Foundation. The position is 22 months at a 100% workload, or longer at an 80% workload. No specific salary or tuition information is stated.
What's required
Applicants should have research experience in ecology and evolution and an earned doctorate, or expect to finish a PhD by early 2027, in a relevant field of biology, ecology, or environmental science. A strong interest in fish migration ecology, excellent English communication and writing skills, data analysis skills, and the ability to work in a team are essential. Knowledge of salmonid migration life history is beneficial. Prior experience with otolith microchemistry is advantageous but not required. Applications should include a scientific-interest letter, CV with publication list, and the names and contact information of two references.
How to apply
Submit the application through the online application webpage by 30 November 2026. Include an application letter describing your scientific interests and relevance to the position, a CV with publication list, and the names and contact information of two references.
