PhD Position in Aquatic Ecology and Microbiology at Linnaeus University, Sweden

Linnaeus University in Sweden is offering a fully funded doctoral student position in Ecology, with a research focus on aquatic ecosystems, vitamin deficiency in animals (especially salmon), and the interplay between diet, microbiota, and environmental factors. The project is based in the Department of Biology and Environmental Science, a multidisciplinary department with expertise in aquatic ecology, microbiology, evolutionary biology, and environmental science. The research is funded by the Swedish Research Council and will involve laboratory experiments, field studies, and mathematical modeling to investigate thiamine (vitamin B1) deficiency in salmon and its ecological consequences. The project includes collaboration with researchers in the United States and Norway. Applicants should have a Master’s degree or equivalent experience in aquatic ecology or a closely related field, with documented knowledge in ecology or biology and proficiency in English. Merits include experience in scientific publishing, fish physiology, HPLC measurements, sampling and experiments involving fish or aquatic systems, mechanistic laboratory experiments, molecular and microbiological methods, Matlab and/or R software, statistical analyses, general fieldwork, and a driver’s license. The successful candidate will join a collaborative research group and benefit from Linnaeus University's strong connections to both local and global research communities. The position is full-time and limited in duration according to Swedish higher education regulations. The application must be written in English and include a CV, personal statement, documentation of exams and grades, a copy of the passport, and contact details for two referees. The deadline for applications is February 20, 2026. For more information, contact Associate Professor Samuel Hylander or Biträdande prefekt Andreas Svensson.
