PhD positions in Marine Microbiology

Job announcement  (Bio-03/2013)

The Microbial Ecology Group of the Department Biological Oceanography of the Leibniz-Institute for Baltic Sea Research Warnemünde (IOW) is offering    


2 PhD positions in Marine Microbiology

starting on October 1, 2013. Remuneration is paid in accordance with the TV-L salary scale at level EG 13. The employments are temporary for 3 years.

The IOW is an independent institute of the Leibniz Association, which focuses on coastal and marginal seas, notably the Baltic Sea is investigated. The scientists of the four sections (Physical Oceanography, Marine Chemistry, Biological Oceanography and Marine Geology) work interdisciplinary within a common research program and with the support of a special working group for the development of new technologies. The advertised positions are embedded within two projects funded by the German Science Foundation (DFG):


1) The project „Microbial diversity and function within the salinity gradient of the Baltic Sea“ (MicroFun) deals with the question how the salinity gradient of the Baltic Sea impacts the structure and function of the pelagic microbial communities. This will be examined, in ship-board experiments during research cruises and in laboratory studies, by applying molecular, microbiological and biogeochemical techniques. One focus will be to link the physiology and function with the identification of dominant prokaryotes  (e.g., by RNA-SIP, NanoSims, Microautoradiography and CARD-FISH).


2) The project „Impact of lateral intrusions and mixing on the biogeochemistry and microbiology of pelagic redoxclines“ (Redox-Intrusions)

Investigates, in cooperation with physical oceanographers, how mixing processes in marine oxygen deficient zones impacts the activity, community composition and biogeoehemical transformations of the microbial communities.  Experiments will be performed mainly within the frame of research cruises (e.g., to the Baltic and the Black Sea), and involve molecular and microbiological techniques, and the combination of biogeochemical process measurements with gene expression analyses.  



Applicants are expected to have a degree in the fields of microbiology, marine biology, biogeochemistry or similar fields. Experience in the analysis of composition and function of natural microbial communities is advantageous, the capability to participate in research cruises is required.

Applicants are asked to send their complete applications for one or both positions (CV, copies of certificates, references, statement to which project complete list of accepted or published manuscripts in peer-reviewed journals), quoting

Code: Bio-03/2013

Until August 31th, 2013 to:


Leibniz-Institute for Baltic Sea Research Warnemünde Dept. Human Resources Seestraße 15 D-18119 Warnemünde Germany

Applications of disabled persons with same professional and personal qualification will be treated preferentially. Please indicate a handicap in the cover letter and enclose the relevant certificate.

Applications of female candidates are expressly encouraged.

The IOW promotes equal opportunities. Our family office, equipped with computer workstation and toys, offers parents the opportunity to take children to the IOW for shorter periods.

The Leibniz Institute for Baltic Sea Research offers a diverse work environment in the immediate vicinity of the Baltic Sea. Interdisciplinary research topics around the Baltic Sea ecosystem, broad in-house expertise in physical, chemical and biological oceanography, marine geology, test equipment and very good infrastructure and facilities provide a framework for best research conditions.

Application and travel costs cannot be reimbursed.
