Your personal sphere of influence:
The Division of Microbial Ecology (

The contract for this position is limited to 3 years.

Your future tasks:
The postdoctoral researcher will be working on developing biochemical methods to study the metabolism of nitrifying bacteria and archaea. As a significant part of these processes takes place in the cellular membrane, this will require the development of biochemical assays compatible with membrane proteins. Moreover, these model systems should be compatible with cryo-electron microscopy so that both the biochemical activity and structural changes of the proteins can be studied within the same system. In addition to the challenge posed by the membrane environment, metabolic activity often depends on the presence of a transmembrane proton gradient and an electrostatic potential difference across the lipid bilayer. An additional goal of this postdoctoral project will be to develop model systems in which these gradients can be established, manipulated, and measured.

This is part of your profile:
Experience in protein purification and working with membrane proteins
Experience in sample preparation techniques for cryo-electron microscopy and should be familiar with the software used to process cryo-EM data and building protein structures
The ideal candidate will also be familiar with the metabolism of nitrifiers and have experience in developing biochemical assays to study protein activity
Experience working with model systems of the cellular membrane such as liposomes or submitochondrial particles is considered a plus
PhD in a relevant field

What we offer:
Access to diverse facilities for state-of-the-art analyses and unique instruments for single-cell activity assays such as NanoSIMS.

A diverse and stimulating work environment at the Centre for Microbiology & Environmental Systems Science, in the Division of Microbial Ecology.

Internal further training & Coaching: Opportunity to deepen your skills on an ongoing basis. There are over 600 courses to choose from – free of charge.

Fixed-term contract and fair salary: The basic salary of EUR 5.014,30 (gross salary on full-time basis,14 times a year) increases if we can credit professional experience.

Equal opportunities for all: We look forward to diverse personalities in the team.

It is that easy to apply:
Your application should consist of a letter of motivation (1-2 pages), your CV including a publication list, university certificate(s) including grades and contact information of two references. The letter of motivation should address the stated qualifications for the position, relevant experience and research interests.
