Postdoctoral / Doctoral Researcher in cell and molecular biology, Vartiainen group
Postdoc @University of Helsinki posted 3 days agoJob Description
The position
A Postdoctoral and/or Doctoral Researcher position is available in the lab of Dr. Maria Vartiainen at the Institute of Biotechnology, University of Helsinki, Finland (https://www.helsinki.fi/en/researchgroups/nuclear-organization-by-actin). We are seeking a motivated researcher to join our team in the field of cell and molecular biology. By combining advanced imaging techniques with functional genomics, we study how actin operates in the nucleus to regulate nuclear organization and consequently nuclear processes. The successful candidate(s) will focus on the mechanisms by which actin regulates the activity of specific transcription factors using cell biological and sequencing-based (RNA-seq, ChIP-seq, CUT&RUN, PROseq) techniques.
Qualifications
We invite applications from candidates with a strong theoretical background and a degree in cell and molecular biology (or similar field) and preferably some practical experience in cell culture and/or functional genomics methods. For the Doctoral Researcher position, we may also consider candidates who are interested in first doing their MSc theses on the topic.
Contract & salary
The position is available from 1.9.2025 and can continue until August 31, 2029.
The salary of the positions will be based on salary system of Finnish universities for teaching and research personnel. In addition, the appointee will be paid a salary component based on personal performance.
How to apply
Applications are to be sent as a single PDF-file by August 15, 2025, using the University’s recruitment system via the button “Apply now”. The application should include a short cover letter (max 1 page) describing your expertise and motivation for the position, a CV (max 2 pages), and the names and contact information for at least two references.
Applications will be reviewed on a rolling basis, and the position may be filled before the deadline if a suitable candidate is identified.
