Postdoctoral researcher in microbial biogeochemistry

Über uns

The ICBM is an interdisciplinary research institute for fundamental and applied marine research. The internationally renowned institute aims at understanding the function of marine environmental systems through close cooperation of the various scientific disciplines (chemistry, biology, physics, mathematical modelling) of its more than 20 research groups.

The research group for Marine Geochemistry (ICBM-MPI Bridging Group) investigates the biogeochemistry of dissolved organic matter (DOM). Main tools are ultrahigh-resolution mass spectrometry (Fourier-transform ion cyclotron resonance mass spectrometry, FT-ICR-MS), high field nuclear magnetic resonance spectroscopy and complementary chemical analytical approaches, combined with multivariate statistics and numerical modelling.

Ihre Aufgaben

The postdoctoral researcher will study how bacteria evolve to use individual compounds within DOM and themselves transform the molecular composition of DOM in aquatic ecosystems in the framework of the ERC project sEEIngDOM. The project will combine field studies with laboratory experiments to understand the environmental conditions that influence the ecology of molecules. 

Responsibilities of the successful candidate include participation in sampling campaigns and joint laboratory experiments; the processing, analysis, and interpretation of samples for DOM molecular composition; and the design, processing, and analysis of shotgun metagenomics, amplicon, and transcriptomics datasets. 

Ihr Profil

Recruitment requirements:

• A doctoral degree (PhD or Dr. rer. nat.) in environmental sciences, biogeochemistry, biology (ecology and evolution), and related disciplines
• A Master of Science in microbiology
• Very good English language skills (written and spoken, TOEFL level C1 or comparable qualification)
• Experience with geochemical sample processing and analysis, preferably under trace clean conditions
• Experience in DNA/RNA sequencing using both Oxford Nanopore and Illumina platforms
• Experience in flow cytometry for enumeration of microorganisms
• Experience undertaking experimental evolution studies with microorganisms, including culturing bacteria
• Familiarity with ultrahigh-resolution mass spectrometry and genomics
• Advanced knowledge of bioinformatics and statistics, including programming with R or Matlab

Desirable qualifications:

• Willingness to carry out field work, including under harsh conditions in remote locations
• Willingness to work in an interdisciplinary and international team, good communication skills
• Familiarity with laboratory experiments combining microorganisms with complex organic matter sources
