Job Summary

This doctoral researcher position, funded by the DFG, focuses on understanding the biochemical mechanisms of metalloenzymes in marine microbial metabolism, crucial for assessing ocean productivity and the global Earth system's development. The role involves investigating the growth of marine microbes under varying nutrient conditions (e.g., phosphorus and metals), analyzing the molecular mechanisms of microbial metalloenzymes using techniques like (meta-)proteomics and metallomics, and integrating these findings into global processes. Day-to-day tasks include sterile cultivation of marine microorganisms, recombinant expression of enzymes, conducting experiments in certified clean rooms under trace metal-clean conditions, and participating in field sampling aboard research vessels. The ideal candidate holds a Master's degree in a relevant scientific field and possesses strong laboratory experience in biochemistry, including microbial cultivation, protein expression, enzymatic assays, and data handling. This position offers the opportunity to earn a Ph.D. in Natural Sciences and provides interdisciplinary networking through the FYORD program.
