The Research Training Group (RTG 2530) “Biota-mediated effects on carbon cycling in estuaries” is inviting applications for 14 PhD positions (f, m, d). Applicants should have a keen interest in interdisciplinary research on the role of effects of biota on estuarine carbon cycling. The 14 doctoral projects built on the results of the first two cohorts of doctoral researchers. Doctoral researchers comprise empirical studies at established research stations along the Elbe estuary, carry out (joint) mesocosm studies, laboratory experiments and/or further develop and apply mechanistic ecosystem modelling. Specific focus in this third cohort of doctoral researchers is on “trophic control of carbon fluxes”, on “biota-mediated aquatic-terrestrial coupling” and on “spatial and temporal upscaling approaches”.

We are offering:

• an excellent research environment
• supervision by an interdisciplinary team
• a structured study program with RTG lectures, lab and field courses

Position Details:

• Institution:Faculty of Mathematics, Informatics and Natural Sciences, Department of Biology and Department of Earth System Sciences
• Start Date: April 1, 2026
• Duration: 3 years
• Salary level: 65% of a 13 TV-L position 
• Application deadline: Various dates in November 2025 (see details on each PhD position below)

Candidates should:

• be highly motivated and keen to work in an interdisciplinary research environment
• have an interest in carbon cycling and are not scared to work in the field in all weathers
• be fluent in English

Your application should comprise the following documents:
