  • Subjects Marine Ecology Description GEOMAR Helmholtz Centre for Ocean Research Kiel is a foundation of public law jointly financed by the Federal Republic of Germany (90 %) and the state of Schleswig-Holstein (10 %) and is one of the internationally leading institutions in the field of marine sciences. Currently GEOMAR disposes over an annual budget of approx. 80 million Euro and has approx. 1000 employees.

    The research unit Ocean EcoSystems Biology of the research division Marine Ecology is offering two positions as

    Doctoral researcher (m/f/d) in Marine Microbial Ecology

    starting on February 15th, 2022 or as soon as possible. The positions offer the possibility to attain a doctoral degree in natural sciences.

    Project Description • Marine microbial interactions are a key factor controlling the fate of energy and nutrients in the ocean ecosystem. These communities are extremely diverse but we still know little about ‘who is interacting with whom'. The offered positions will play an important role in advancing an understanding of the ecology and evolution of marine microbial interactions. One goal of this project is to develop, evaluate, and apply 'high throughput microcosm approaches to experimentally and mechanistically examine interactions in the plankton, their specificity, prevalence, and mechanisms'. Another goal is to 'develop and apply state-of-the-art single cell resolved approaches to explore physical interactions in the plankton, their specificity, and prevalence'. The research will study these topics in diverse marine time-series and ecosystem contexts. • The advertised positions will contribute to Helmholtz Young Investigator Group lead by Dr. David Needham at the GEOMAR Helmholtz Centre of Ocean Research Kiel.

    Qualification Required: • Master's degree in the field of microbiology, biological oceanography, ecology, molecular biology, or similar

    Preferred: • Experience in lab for molecular biology, nucleic acid extraction, PCR analyses, (meta)-omics, and library prep • Experience with computational approaches for processing high-throughput amplicon and/or -omics based data and their interpretation • Familiarity with command line software, bash scripting, R and/or python • Experience in microbial cultivation • Ability and enthusiasm to work in the field at research stations or aboard ships frequently or for periods of time spanning weeks • Experience in flow cytometry, cell enumeration • Socially-conscious, supports an equitable, inclusive and collaborative research environment

    The position is available for a funding period of three years. The salary depends on qualification and could be up to the class E13 TVöD-Bund of the German tariff for public employees. This is a part-time position according to 75% of a full-time equivalent. The position can not be split, flexible working time models are possible in principle. The fixed term contract shall comply with Section 2 Paragraph 1 of The Act of Academic Fixed-Term Contract (German WissZeitVG).

    GEOMAR Helmholtz Centre for Ocean Research Kiel seeks to increase the proportion of female scientists and explicitly encourages qualified female academics to apply.

    GEOMAR is an equal opportunity employer and encourages scientists with disabilities to apply. Qualified disabled applicants will receive preference in the application process.
