The Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) is the largest freshwater research institute in Germany. It is a member of the Forschungsverbund Berlin e.V. (FVB) and the Leibniz-Association. The FVB manages 8 large research institutes in Berlin that have close links to all three major universities in the German capital. IGB offers excellent laboratory and field facilities for interdisciplinary research, large-scale experimental facilities, and long-term research programs and data sets.
Early Stage Researcher (ESR) positions are available to be trained and perform research in hydrological and biogeochemical processes at aquatic interfaces within the Marie-Curie Initial Training Network (ITN) INTERFACES at the IGB. The successful candidate will tackle scientific and technical challenges spanning from lab experiments to remote sensing, from biology to mathematics, from centimetre scales to catchments.
DescriptionWithin the 7th Framework programme the ITN INTERFACES focuses on “Ecohydrological interfaces as critical hotspots for transformations of ecosystem exchange fluxes and biogeochemical cycling”. In total, the network involves 11 PhDs and 4 Postdocs located across 7 countries in Europe. The INTERFACES consortium assembles an unprecedented network of world-leading research centres, universities, private sector companies and public sector partners to provide outstanding joint expertise and training environment in the fast-moving field of ecohydrology. The participants of INTERFACES are internationally renowned experts and have long-standing interdisciplinary expertise in the research of complex transport and transformation processes of water and energy fluxes and interlinked biogeochemical cycles at ecohydrological interfaces. The main research goal of INTERFACES is to advance interdisciplinary development and application of innovative technologies for sensing and modelling heat fluxes, metabolism, biogeochemical turnover and ecological functioning to understand how and to what extent system interfaces act as critical hotspots for water-dependent environmental processes. Our vision is to generate new interdisciplinary understanding of interactions between heat fluxes, microbial metabolism, biogeochemical cycling and ecological functioning across coupled water-dependent system boundaries. It is our goal to quantify (a) the importance of these interfaces as critical hotspots for environmental processes dynamics and (b) the sensitivity of these hotspots to global change.
Some organisms living in lake sediments have great impacts on the entire lake ecosystem. Chironomus plumosus larvae build U-shaped burrows through which they pump enormous amounts of water. The PhD student will study the transport of nutrients and carbon across the burrow walls and the turnover of matter in the surrounding sediment with the aim to identify biogeochemical hot spots along the burrows. A further aim is to test whether phosphorus fixed by redox-sensitive immobilization along the burrow course will be remobilized after reestablishment of anoxic conditions after emergence of the larvae or if, on the contrary, a significant amount of phosphorus is permanently removed by chironomid activities. Impacts of chironomids on oxygen, phosphorus, nitrogen and carbon turnover will be studied, based on 15N and 33P stable isotope techniques and smart tracer approaches. The PhD candidate will be co-supervised by a researcher of the University of Birmingham and will stay there in total approximately 3 month and additionally some further month at other partners of the INTERFACES consortium.

BenefitsThe successful candidate will be employed for three years and receives a generous financial package plus an additional mobility allowance according to the rules for Early Stage Researchers (ESRs) in an EU Initial Training Network (ITN) (see http://cordis.europa.eu/fp7/mariecurieactions/library_en.html). He/She will have access to a set of training activities organized within the INTERFACES consortium as well as to the PhD programme of the IGB. IGB has an intensive PhD training programme and more than 50 PhD students are employed at IGB. Within the employment there will be the option to acquire a PhD at the Humboldt University Berlin.
Additional Job DetailsEnvisaged starting date between 1-Jan-2014 and 1-May-2014.
Applications will be reviewed in batches every month until the vacancy is filled. Recruitment process will include an interview with shortlisted candidates.
At the time of recruitment by the host organisation, candidates must be in the first four years (full-time equivalent research experience) of their research careers and must not have obtained a PhD or equivalent. Because the Marie Curie schemes are designed to encourage inter-European mobility, there is an eligibility condition for recruitment: “at the time of recruitment by the host organisation, researchers must not have resided or carried out their main activity (work, studies, etc) in the country of their host organisation for more than 12 months in the 3 years immediately prior to the reference date”.
Applications or informal enquiries should be addressed to Dr. Jörg Lewandowski (preferably by email, email@example.com) making sure to cc in your email firstname.lastname@example.org. Questions on the application process should be sent to email@example.com.
