Postdoctoral position available in the Mittag lab, Friedrich Schiller University Jena

Scientific staff member (100% Postdoctoral position)


Albeit microalgae are key contributors to global carbon fixation, their molecular interactions with other microbes in various ecosystems are still little known. In the framework of the CRC ChemBioSys (, we have investigated the interplay of the green alga Chlamydomonas reinhardtii with other microorganisms and found that Pseudomonas protegens strongly inhibits algal growth. The bacteria secrete natural products including a cyclic lipopeptide that causes Ca2+ signals and deflagellation as well as a polyyne blinding and lysing the algal cells (Aiyar et al., Nat. Commun. 8, 1756, 2017; Rose et al., Environ. Microbiol. 23, 5525-5540, 2021; Hotter et al., Proc. Natl. Acad. Sci. USA 118, e2107695118, 2021; Bando et al., Chem., doi: 10.1002/chem.202104417, 2022). We also established a marine Chlamydomonas sp. as genetically tractable model (Carrasco Flores et al., J Phycol, 2021, doi: 10.1111/jpy.13083). We now aim to study involved signaling pathways in Chlamydomonas reinhardtii, focus on bacterial virulence and its neutralization and investigate biotic interaction in the marine system using Chlamydomonas sp..

Your tasks:

  • Investigate the mode of action of the cyclic lipopeptide and involved Ca2+ channels
  • Bacterial virulence: Study the influence of macronutrients and helper bacteria
  • Investigate bacterial interactions with the marine Chlamydomonas

What we expect:

  • PhD, Dr. rer.nat. or a comparable doctoral degree in molecular biology, cell biology, botany, phycology, microbiology or a related subject.
  • The candidate should be highly motivated. Experience with methods of molecular biology, microbiology and biochemistry are desired.
  • A very good knowledge of English is expected.

We offer:

  • A top-level research environment
  • Close interactions with the involved institutions of the SFB (
  • Attractive fringe benefits such as capital accumulation benefits, job tickets for reductions in public transport, employer-funded pension (VBL)
  • University health promotion and a family-friendly working environment with flexible working hours
  • The position will be financially supported according to TV-L (salary agreement for public service employees) till salary scale 13.
  • The employment is limited to four years. Applications from physically handicapped persons will be considered preferentially in case of equal qualifications and suitability.
