Postdoctoral position in mechanistic studies of DNA replication

Updated: 4 months ago
Location: Sweden,
Job Type: FullTime
Deadline: 23 May 2023

The Department of Medical Biochemistry and Biophysics at Umeå University, Sweden, invites applicants for a two-year Postdoctoral position in mechanistic studies of DNA replication. The position is expected to start as soon as possible or according to agreement. Application deadline is May 23rd 2023.

Description of the project

Re-replication is a major threat to genome stability. Recently we found that single-strand breaks in the form of nicks may cause localized re-replication by an, until recently, over-looked mechanism1. Considering that nicks are estimated to be the most common DNA lesions in eukaryotic cells, DNA replication forks are bound to encounter nicks. Here we will explore the mechanisms by which eukaryotic cells may suppress re-replication when replication forks encounter un-repaired nicks. If not functional, this could be one underlying cause for copy number variations and gross chromosomal rearrangements often found in cancer cells.

Both yeast genetics and biochemical studies will be applied to uncover pathways that may suppress re-replication in the event when a replication fork encounters an unrepaired nick ( ).

Work responsibilities

Depending on the applicant´s background and interests, the focus will be on either yeast genetics or biochemical studies. The tasks will include the construction of plasmids and yeast strains, followed by genetic assays where we score the frequency by which gene duplications occur. The biochemical approach includes over-expression and purification of proteins that are or may be involved in the pathway that we study. This will include experiments with the reconstituted eukaryotic replication fork.


A person who has been awarded a doctorate or a foreign qualification deemed to be the equivalent of a doctorate within biochemistry, cell- and molecular biology, genetics, or related discipline, is eligible for appointment as postdoctoral researcher. This eligibility requirement must be met no later than the time at which the appointment decision is made.

 We seek highly motivated candidates with experience in purifying and working with recombinant proteins or in yeast genetics. Experience within the field of DNA replication or DNA repair is advantageous. You should have a strong relevant research output, as evidenced by first authorship, on publications presenting ground-breaking new research findings or new molecular biology tools.

Candidates must be fluent in spoken and written English. Since the project will be of collaborative nature, candidates are expected to function in a team and therefore have a good ability to cooperate. Excellent communication skills are required for interacting effectively with colleagues and peers, including colleagues from complementary research fields. Good initiative ability is a requirement.

Additional useful qualifications

Since appointment as a postdoctoral researcher is a career-development position for junior researchers, we are primarily interested in applicants who completed their doctoral degree no more than three years before the application deadline. If there are special reasons, an applicant who has completed their degree earlier than that may be considered. Special reasons include absence due to illness, parental leave, clinical practice, appointments of trust for a trade union organisation or other similar circumstances, and for relevant duties/assignments within the subject area.

More information about the position

The appointment is a full-time, fixed-term position for two years in accordance with the terms of contract for fixed-term employment as a postdoctoral researcher.

The application must include:

  • A personal cover letter explaining why you are interested in the fellowship, how you can contribute to the project and in which direction you may want to develop it (no more than 2 A4 pages).
  • A curriculum vitae that documents academic education and past and previous employments.
  • A list of your publications.
  • A copy of the PhD certificate and other relevant degree certificates.
  • Names and contact details with e-mail addresses of two or three academic references.
  • Other relevant documentation you wish to include in support of your application.
  • The application must be written in Swedish or English. The application must be made via our e-recruitment system Varbi ( ) and must be received latest May 23rd 2023.

    If there are questions, please contact Prof Erik Johansson, .
