Doctoral researchers in the DFG Graduate Program “Biota-Mediated Effects of Carbon Cycling in Estuaries (RTG2530) – Effects on biotic and abiotic C and nitrogen sources on GHG fluxes across terrestrial-aquatic boundaries” § 28 Subsection 3 HmbHGInstitutionFaculty of Mathematics, Informatics and Natural Sciences, Department of Earth System Sciences, Institute of Soil ScienceSalary levelStart date01.04.2026, fixed until 31.03.2029 (This is a fixed-term contract in accordance with Section 2 of the academic fixed-term labor contract act [Wissenschaftszeitvertragsgesetz, WissZeitVG]).Application deadline30.11.2025Scope of workpart-timeWeekly hours65 % of standard work hours per weekThe overall mission of the Research Training Group 2530 (RTG 2530) is to fill existing knowledge gaps on biota-mediated effects on estuarine C cycling under current conditions and with respect to global change scenarios. Embedded into the inspiring academic environment of the University of Hamburg, RTG 2530 provides Doctoral and Postdoctoral Researchers an outstanding platform for their career development. The RTG has been established by an interdisciplinary group of 17 Principal Researchers with scientific backgrounds ranging from terrestrial and marine ecology, via geoscience to microbiology and molecular animal biology. The RTG is funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG). Currently, we have 14 open positions (TVL E13, 65%) for doctoral researchers (see ).Your responsibilitiesActive participation in a structured graduate program. The doctoral researcher will be a member of RTG 2530 and the Aquatic nutrient Cycles department at the Helmholtz-Zentrum Hereon in Geesthacht, where the work place for this position is located. The candidate shall investigate the production of nitrous oxide and methane and their dependence on environmental drivers in water and sediments of the Elbe and transition zones in a combination of field and laboratory studies. The project aims to identify anthropogenic drivers of greenhouse gas emissions and possible linkages to eutrophication phenomena. Planned field and lab measurements include laser-based and gas-chromatographic greenhouse gas measurements and incubations of water, sediment, and floating chamber measurements in the field.Your profileA university degree in the field(s) of Biology, Geosciences, or Environmental Sciences or comparable disciplines. The successful candidate should have knowledge and experience in aquatic sciences, biogeochemistry and/or environmental sciences. Experience in water biogeochemistry, e.g. greenhouse gas analysis and/or nutrient turnover processes and respective field and laboratory methods are beneficial. Team spirit, experience with field work and scientific writing and knowledge with R or similar software is a plus. Good oral and written English skills and the willingness and ability to participate in research cruises are necessary.We offerReliable remuneration based on wage agreementsContinuing education opportunitiesUniversity pensionsAttractive locationFlexible working hoursWork-life balance opportunitiesHealth management, EGYM WellpassEducational leave30 days of vacation per annum a structured and interdisciplinary program with colloquia and workshops an inspiring university environment with international visiting scholars funding for international research stays for members of the Research Training Group excellent research infrastructure with administrative offices, shared workspaces and an attractive working environment a wide range of support services during the doctoral phase and national and international continuing education and training opportunities participation in cultural and scientific university events Universität Hamburg—University of Excellence is one of the strongest research educational institutions in Germany.
