About this position
Research Assistant (f/m/d) / PhD student position at the University of Bremen, MARUM – Center for Marine Environmental Sciences, in the project “Diversity and function of fermenting microorganisms in Antarctic marine sediments”.
The project is part of the DFG Priority Programme Antarctic Research and focuses on microbiology, biogeochemistry, marine sediments, microbial ecology, and polar research. The work combines geochemical analyses, 16S rRNA gene sequencing, qPCR, and RNA-based stable isotope probing (RNA-SIP) with 13C-labelled organic material to identify fermentative microorganisms and understand their role in anaerobic food webs and Antarctic coastal sediment processes.
Main tasks include sampling and geochemical analysis of Antarctic sediment samples, incubation experiments, stable isotope probing, sequence analysis, and participation in fieldwork on the Antarctic Peninsula at Carlini Station. The position also involves collaboration with MARUM colleagues, the DFG programme, and Argentinian partners, plus presenting results at meetings and conferences and publishing in peer-reviewed journals.
Eligibility: a completed Master’s degree or equivalent in biology, microbiology, biogeochemistry, or a related field; final-stage Master’s students may apply, but the degree certificate is required before employment. Applicants should have experience with sampling and incubation experiments, strong English skills, teamwork ability, and communication skills for an international environment. Helpful extras include expedition experience, R/Python/Bash/Linux data analysis, basic knowledge of polar microbiology or marine sediments, and Spanish.
Funding: paid TV-L 13 position at 75% working time for 3 years, with additional public-sector benefits. Deadline: 29 September 2026. Apply by sending a single PDF with all required documents and two references to [email protected] (reference A166-26).
