The Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) is the largest freshwater ecology research institute in Germany. It is a member of the Forschungsverbund Berlin e.V. and the Leibniz-Association ( The FVB manages 8 large research institutes in Berlin that have close links to all three 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.

IGB invites applications for a

PhD position in Evolutionary Biology
 “The Evolution of Virulence under Conditions of Frequent Multiple Infections

The position is available from 1st January 2018 and limited to 3 years.

Project Description

Interactions between multiple parasite species (infecting the same host) can affect the evolutionary trajectory of virulence, with important ecological and epidemiological consequences. The goal of the proposed work is to elucidate implications of multiple infections on the evolution of (parasite) virulence. The successful candidate will use a combination of experimental evolution and field approaches to generate new and refined predictions regarding the virulence of parasites that spread into new habitats, where they encounter co-infecting parasites. He/she will use a model system consisting of the crustacean Daphnia and their microparasites. The proposed research is a collaboration between German and Israeli scientific teams: Prof. Justyna Wolinska from IGB and Freie Universität Berlin ( and Dr. Frida Ben-Ami from Tel Aviv University (, financed by the German Science Foundation (DFG). The position is mainly based in Berlin; however, a two-month research stay at the Tel Aviv University is planned. Funding for attending national/international conferences is available.

 Duties and responsibilities

  • laboratory experiments
  • field work (investigating geographical patterns of co-infections)
  • advance statistical analyses of experimental (life history and genomic) and field (environmental and genetic) data


  • MSc degree in biology, bioinformatics or related field
  • strong background in evolutionary biology, population genetics or ecology
  • hands-on experience with experimental work
  • experience in molecular or genomic research would be an advantage
  • excellent analytical skills and very good knowledge in statistics
  • a basic knowledge in bioinformatics or programming would be advantageous
  • excellent communication and writing skills in English
  • good work ethic
  • creative thinking

Salary is paid according to the TVöD (65% position). In keeping with the IGB's policy regarding gender equality, female applicants are particularly encouraged. Severely disabled applicants with equal qualification and aptitude are given preferential consideration.

Enquiries or questions should be directed to Prof. Justyna Wolinska (
