to commence at the earliest possible date. The position is limited for three years.

Your Duties:

  • Participate in the DFG-funded project “Eco-evolutionary causes and genomic consequences of synergistic coevolution“
  • Perform coculture and coevolution experiments with different bacterial strains
  • Reconstruct mutations in different genetic backgrounds
  • Conduct growth experiments to analyse fitness consequences of mutations
  • Determine the cooperativity of bacterial strains by quantifying their amino acid production rates (LC-MS/MS)
  • Spatio-temporal analysis of bacterial aggregates using tools of microfluidics and fluorescence microscopy
  • Flow cytometric analyses
  • Close collaboration with cooperation partners Dr. Alexander Herbig (Max Planck Institute for Evolutionary Antrhropology) and Dr. Alexander Grünberger (Karlsruhe Institute of Technology)
  • The successful candidate will have the opportunity to work towards a PhD


  • Completed degree (M.Sc. or comparable) in biology or a related field
  • Solid practical experience in microbiological techniques and molecular biological methods
  • Excellent command in written and spoken English

Additional Qualifications:

  • Sound knowledge of ecological and evolutionary concepts and theory
  • An excellent university degree
  • Creative way of working
  • Strong motivation and curiosity
  • Ability to work in an interdisciplinary team
