Biologist (Doctoral Researcher) | Biologe (m/w/d)

Job Summary

This doctoral researcher position, funded by the DFG, focuses on investigating the role of marine photosynthetic microorganisms in global biogeochemical cycles, particularly concerning phosphorus and trace metal scarcity. The successful candidate will conduct research aimed at understanding the biochemical mechanisms of metal-dependent enzymes in microbial nutrient metabolism to predict marine productivity under global change. Day-to-day tasks include sterile culturing of marine eukaryotes and prokaryotes, recombinant expression and biochemical characterization of metalloproteins, and advanced (meta-)proteomics and metallomics analyses using mass spectrometry and bioinformatics. The role involves laboratory work under trace-metal clean conditions, field sampling on research vessels, and presenting findings in scientific journals and conferences. This is an attractive opportunity to attain a doctoral degree in natural sciences within the internationally leading GEOMAR Helmholtz Centre, offering collaboration with international partners and enrollment in the FYORD career development program.
