The research group ‘Eco-Evolutionary Dynamics’ at the Department of Evolutionary and Integrative Ecology of IGB invites applications for a 3-year PhD position in Experimental Eco-Evolutionary Dynamics starting earliest March 2023. The research group is located in Berlin-Friedrichshagen at Lake Müggelsee. We are seeking a highly motivated person who has a keen interest in questions about eco-evolutionary dynamics and has a passion for science.

The PhD project centres around eco-evolutionary community dynamics with a strong focus on experimental work using multiple species of freshwater unicellular ciliates. The project will investigate when we should expect a strong interaction between selection and species sorting in multi-species communities undergoing environmental change. The project combines large microcosm experiments with automated video analysis in which phenotypic trait data and species densities are collected, followed by in-depth statistical analyses. The successful candidate will work closely together with a second PhD candidate focusing on developing theoretical models fitting to the experimentally collected data.

Your tasks

  • Design and perform microcosm experiments using freshwater unicellular organisms tackling highly novel questions in eco-evolutionary dynamics
  • Analyse large data sets and report results in scientific publications and conferences
  • Maintain cultures of freshwater ciliates
  • Prepare a doctoral dissertation

Your profile

  • Master (or equivalent) degree in Biology, Aquatic or Environmental Science, or a related field
  • High interest in eco-evolutionary dynamics and experimental designs
  • Experience in conducting experiments with living organisms
  • Knowledge in data/statistical analysis (in R or Python)
  • Experience with handling large data sets is of advantage.
  • Problem-solving mindset
  • The working language of the group is English, and suitable reading, writing (including scientific writing) and speaking skills are required
  • Engaged person with a team-spirit

Our offer

We offer an exciting position in an international and dynamic scientific environment including excellent equipment and technical support. Your career development is fostered by qualification and training opportunities. We actively support the reconciliation of work and family life.

The position is for 3 years with a starting date earliest March 2023. Salary is paid according to the German salary scheme for the public sector (65% E 13 TVöD Bund).

“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 97 independent public research institutes in Germany.
