Anaerobic ammonium oxidation & methanogenesis stimulated by redox-active iron mineral nanoparticles

We will carry out laboratory batch and bioreactor experiments with geochemical and molecular analyses (qPCR, metatranscriptomics) to follow microbial growth and activity, NH4+ removal and CH4 production efficiency. In addition, the nanoparticles will be analyzed (wet-chemistry, electron microscopy, XRD, Mössbauer spectroscopy).

The PhD student will be given opportunities to be creative and innovative, to apply state-of-the art microbiological and geochemical analyses, molecular techniques, microbial physiological studies, microscopy, and spectroscopy.

Requirements:

• Strong background in Environmental Microbiology, Microbial Ecology and Geochemistry.
• Ability to work independently and in a team.
• Excellent management and communication skills.
• Highly motivated for interdisciplinary research.
• Good computer and language (English) skills.

Start date for successful applicant is March 2025 (or as soon as the candidate is available). Employment (TVL E13, for 3 years; 75%) will be arranged by the University of Tübingen.
