The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) is invites applications for a PhD position focussing on flux and transformation of phosphorus in urban systems. The position is based at the Department of Chemical Analytics and Biogeochemistry in Berlin. Funding has been secured for 3 years.

We seek to recruit an excellent and highly motivated doctoral student with an interest in interdisciplinary work. The project will focus on the interplay of microbial and chemical mechanisms to forming P minerals. The results serve as basis for innovative managing of eutrophication and P recovery in urban areas. The position is part of a graduate school funded by the German Research Foundation (DFG) as part of the Research Training Group “Urban Water Interfaces” (UWI). The consortium involves multiple fellow students, scientists and engineers at IGB and the Berlin Institute of Technology (TU Berlin).

“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 an internationally leading research centre for freshwaters. We seek to understand the fundamental processes governing fresh waters 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 north of the city. 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.
