The Faculty of Biology of the University of Freiburg is offering a

Post-doc position in the area of Microbiology: Infection mechanisms of archaeal viruses.

Fulltime position, Starting-date: at the earliest possible date

The research group ‘Archaeal virus host interactions’ is studying infection mechanisms of archaeal viruses. Archaea are ubiquitous microorganisms that form a separate domain of life. Compared with bacteria and eukaryotes, relatively little is known about the cell biology and ecological roles of archaea. A prominent feature of archaea is the extraordinary diversity of their viruses. Archaeal viral particles have many unique shapes not encountered for bacterial and eukaryotic viruses. We focus on the infection strategies of archaeal viruses and study the molecular mechanisms underlying essential steps of the viral infection cycle, such as attachment, entry and release of the host cell. Since these processes take place at the cell surface, we are also actively studying the archaeal cell surface and surface appendages using the halophilic euryarchaeon Haloferax volcanii as a model. Studying the infection mechanisms of archaeal viruses can provide insight into the evolutionary history of viruses and help to understand adaptation to extreme environments.

In the framework of a recently awarded Emmy Noether grant, we offer an excellent opportunity to engage into an exciting post-doc project that combines microbiology, genetics, microscopy and  biochemical tools in the context of a dynamic and enthusiastic work environment, with state-of-the-art equipment and various chances for national and international scientific collaborations.

We are looking for a post-doctoral researcher for this project. Your responsibilities will include:

  • Study of the mechanisms underlying archaeal viral infection using light and electron microscopy.
  • Live imaging of protein dynamics in archaeal cells to study the spatiotemporal organization of surface structures.
  • Development of genetic tools for archaea.
  • Supervision of doctoral candidates and students with their bachelor*s or master*s degree
  • Coordination of our laboratory

Your profile includes:

  • A doctoral degree in biology
  • A strong publication track-record.
  • Expertise in virus isolation, microbiology or light/electron microscopy.
  • Eagerness to work in an interdisciplinary and international team
  • Good self-organization and the ability to work independently.
  • Fluency in English.

Please hand in:

  • Letter of intent detailing why you are interested in this specific project and how your previous research qualifies you for the project (up to 1,500 words)
  • Curriculum Vitae with list of publications (if applicable)
  • Certified copies of your university degree(s) with grades (Bachelor and Master certificate/ Diploma certificate and transcript / doctoral certificate)
  • Short summary of your doctoral thesis (up to 1,000 words)
  • Work sample (chapter from recent thesis or journal article, up to 5,000 words)
  • Suggestion of two referees with contact details

Your documents will not be returned after the application process. For this reason, please submit copies only.

The position is limited to 01.04.2020. After positive evaluation, an extension until 01.04.2022 is possible. The salary will be determined in accordance with TV-L E13.

We are particularly pleased to receive applications from women for the position advertised here.

Please send in a complete and convincing application with the above-mentioned supporting documents, by 31.03.2019 at the latest. Please send your application to the following address in written or electronic form:
