For the research group “Groundwater-surface water interactions” of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin-Friedrichshagen at Lake Müggelsee we are inviting applications for a PhD position. The position is part of 13 open positions jointly offered by Technische Universität Berlin and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) within the DFG Research Training Group "Urban Water Interfaces (UWI)" for subproject H5 “Improving retention of trace organics in hyporheic zones of metropolitan areas” starting as of 01. July 2021.

Project H5

The UWI PhD positions are organised in four areas and this PhD position belongs to the area “Interface Urban Hyporheic Zones”. The interface between streams and groundwater (so-called hyporheic zone, HZ) can significantly contribute to the impressive self-purification capacity of streams regarding nutrients and trace organic compounds (TrOCs). The relative contribution of the HZ to in-stream, reach scale TrOC removal is not only dependent on the biogeochemical milieu in the HZ but also on the physical exchange rate between surface water and hyporheic pore water (i.e. the intensity of hyporheic exchange) and thus the reach-scale hyporheic residence time distribution. Thus, river restoration methods aiming at increasing hyporheic exchange are likely to increase the self-purification capacity of urban streams with respect to TrOCs. However, process- and effect-based field evidence with respect to different management strategies to improve HZ exchange is widely lacking.

Your profile

The successful candidate holds an excellent MSc degree in hydrology, hydrogeology, geoecology, geochemistry, environmental sciences or a related field, is looking forward to challenging fieldwork, is experienced in data evaluation and interpretation, has very good oral and written English skills including scientific writing and is excited about the prospect of working in a collaborative team.

Our offer

Salary is paid according to the German salary scheme for the public sector (TVöD Bund). It is a 75% position for doctoral research (salary grade E 13 TvÖD) for three years. We foster your career development by providing qualification and training opportunities. We actively support the reconciliation of work and family life. Applicants are treated equally regardless of gender. Qualified women are particularly encouraged to apply. Severely disabled applicants with equal qualification and aptitude will be given preferential consideration.

Are you interested?

We look forward to receiving your complete application including a letter of motivation indicating research interests and experience and the project key H5, CV including 2 references, a letter of recommendation, Bachelor and Master certificates, and your Master Thesis. Reviews of the applications will begin on 1 March 2021 and continue until the position has been filled. Please upload your application in a single PDF file on the UWI online application platform at

“Research for the future of our freshwaters” is the mission of the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB). The IGB is Germany’s largest and one of the leading international research centres for freshwaters. We seek to understand the fundamental processes governing freshwaters and their communities. Our research findings help to tackle global environmental changes and to develop measures for sustainable water management. The IGB is a diverse and inspiring place to work and conduct research. We promote individual development at every career level and stand for lively exchange and cooperation. With more than 350 employees and guests from all over the world, we conduct research at five locations in Berlin and at Lake Stechlin (Brandenburg). IGB closely collaborates with numerous national and international universities and other partners in science and society and is a member of the Leibniz Association, which connects 96 independent public research institutes in Germany.
