Postdoctoral researcher in environmental microbial ecology

Ansøgningsfrist 29. nov. 23:59 CET

Forventet start 1. feb.

• Institut for Biologi - Mikrobiologi Ny Munkegade 114 8000 Aarhus C
• Tidsbegrænset fuldtidsstilling 1. feb. 2027 - 31. jan. 2029 ID: 170857

The Department of Biology, Aarhus University, Denmark, invites applications for a two-year, fixed-term postdoctoral position in environmental microbial ecology, starting 1 February, 2027, or as soon as possible thereafter. The position is part of a project funded by the Villum Foundation's Villum Experiment programme.

The project
Electrically conductive iron minerals are widespread in anoxic aquatic sediments, yet we know little about the microorganisms that live on them. The project aims to characterize the phylogenetic identity and ecophysiology of microorganisms associated with these minerals. We hypothesize that, by facilitating extracellular electron transfer, the minerals provide a distinct niche that selectively enriches electroactive microorganisms relative to the surrounding sediment.

Expected start date and duration of employment
This is a two–year position from 1 February, 2027, or as soon as possible thereafter.
This is a fixed-term position to end on 31 January, 2029.

Job description
You will identify, visualize and characterize bacterial and archaeal cells associated with iron minerals by combining fluorescence in situ hybridization (FISH) and correlative imaging, DNA- and/or RNA-based omics, and stable isotope incubation experiments. You will have considerable freedom to shape the methodological approach and to develop your own ideas within the project framework. Project collaborators in Germany will contribute chemical characterization of the minerals, giving you the opportunity to work in an interdisciplinary team. Participation in supervision of BSc., MSc. and PhD students and possibly some classroom teaching is also expected.

Your profile
You hold a PhD in biology, earth and environmental science, biotechnology or a related field (or expect to complete it before the start date), and you have a research background in microbiology or microbial ecology.

Essentials:

• Experience with advanced microscopy and/or molecular microbial ecology methods.
• Interest in microbial physiology and electromicrobiology.
• A systematic approach to method development and testing.
• A publication record in international peer-reviewed journals, relative to your career stage.
• Very good written and oral communication skills in English.

Desirable:

• Experience with FISH, correlative microscopy, stable isotope probing, or omics data analysis.
• Experience working with sediment or other environmental samples.
• Experience with microbial physiology and/or electromicrobiology.
• If you are excited about the project but your experience does not match every point, we still encourage you to apply.

At the Department of Biology, we value a collegial and inclusive working environment and place strong emphasis on good relationships among colleagues and students. We welcome colleagues who bring an open, constructive and collaborative approach.

Who we are
The Department of Biology (Aarhus University) provides a framework for research and teaching in all major biological subdisciplines. The department currently encompasses approximately 200 academic and technical staff and 45 PhD students while 400 students follow the BSc and MSc programs offered by the department. The Section for Microbiology () employs 12 associate and full professors and offers a vibrant, international research environment for studying microbial physiology, evolution, ecology, and biogeochemistry. The section integrates basic and applied research, addressing the functions, eco-physiology, and evolution of microorganisms in natural and biotechnological systems. The section has well-equipped laboratories, a permanent support staff of highly skilled laboratory technicians, and access to advanced imaging facilities on the AU campus.

What we offer

• A two-year position in a stimulating, international research environment
• Access to state-of-the-art laboratories and imaging facilities.
• A work environment encouraging lively, open and critical discussion.
• A work environment with close working relationships, networking and social activities.
