Postdoc on the Biogeochemistry of Ammonia-oxidizing Archaea in Oxygen Depleted Environments: Denmark

A two year postdoc position is available at the research unit Nordcee, Department of Biology, University of Southern Denmark. The successful candidate will join a team of scientists studying the ecophysiology and ecology of ammonia-oxidizing archaea in oxygen limited environments funded by a Villum Young Investigator grant to Assistant Professor Beate Kraft.

The project:
Ammonia-oxidizing archaea are key players in the nitrogen cycle of the world’s oceans. They are frequently found in oxygen-depleted environments like marine oxygen-minimum zones or sediments though they are thought to have a strictly aerobic physiology. We found evidence for a so far undiscovered anaerobic metabolic pathway in a cultured representative.

The aim of the postdoctoral project is to identify the activity and distribution of this process in the marine environment. The project has a strong field work component and involves rate measurements using stable isotopes, and tracking of relevant intermediates by microsensor and optode measurements.

The expected starting date is 1 April 2021 or as soon as possible thereafter.

Required qualifications:
Applicants need to have a PhD and a background in environmental microbiology, biogeochemistry, or related fields demonstrated by scientific publications. We are looking for a highly motivated and curiosity-driven candidate with field work experience. Working experience with stable isotope labelling techniques or with microsensor and optode measurements is of advantage. Proficiency in spoken and written English is mandatory.
