Postdoctoral position 2 years

Umeå University is one of Sweden’s largest higher education institutions with over 37 000 students and about 4 700 employees. The University offers a diversity of high-quality education and world-leading research in several fields. And the groundbreaking discovery of the CRISPR-Cas9 gene-editing tool, which was awarded the Nobel Prize in Chemistry, was made here. At Umeå University, everything is close. Our cohesive campuses make it easy to meet, work together and exchange knowledge, which promotes a dynamic and open culture.

The ongoing societal transformation and large green investments in northern Sweden create enormous opportunities and complex challenges. For Umeå University, conducting research about – and in the middle of – a society in transition is what it is all about. But also about delivering education to enable regions to expand quickly and sustainably. This is simply where the future is built.

The Department of Radiation Sciences is looking for a postdoctoral scientist for a project on perinatal epigenetic modulation of gene expression by daylight length. The employment is limited to two years full-time with entry ideally on 1 August 2023 or by agreement.

The host laboratory for Nordic Daylight Research is closely collaborating with the Northpop birth cohort, and scientists from the Umeå Centre for Molecular Medicine, building synergies for excellent research opportunities. We are an interdisciplinary team of field scientists, experimentalists, clinicians and students working on questions about early environmental exposures and child development. We run a systematic data collection pipeline for sleep/activity and light exposure in 3-year old children from which this project benefits in terms of recruitment and data sharing.


We are looking for a postdoctoral scientist who is qualified to contribute their special expertise in analytical biochemistry and biostatistics. We seek to map environmental light doses across day-night phases that make large contributions to photoperiodic pupil sensitivity and differential RNA expression levels. The work shall address sleep and affective susceptibilities to better understand the aetiology of affective disorders. The tasks include:

  • Hair follicle / oral mucosa collection and behavioural and pupil assessment in children  
  • Gene expression assays, real-time RT-PCR, optimisation and validation of assays
  • Possibility to examine blood epigenetic assays
  • Designing computational modelling of time-sensitive data
  • Operating pupil measurements, actigraphic data and parental questionnaires
  • Organising logistics with parents for repeated data collection in children.
  • Seeking ethical approval and adhering to accepted ethical standards in research

Qualification requirements

A person who has completed a doctoral degree or a foreign qualification deemed to be the equivalent to a doctoral degree. This eligibility requirement must be met no later than the time at which the appointment decision is made. 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, unless there are special reasons (for example parental leave).

The doctoral degree must be trained in a biochemistry, molecular biology or related field of life science and has acquired biostatistical skills. Requirements include relevant research results, as evidenced by first authorship of publication that present ground-breaking research results or innovative data-driven methods. Further requirements are:

  • Competence in gene expression assays, real-time RT-PCR
  • Proficient in computational modelling, circular data statistics, nested design and inverse probability weighting methods
  • Proven experience and competence in human research, including interpersonal communication with young children
  • Proficient in Swedish and English
  • Strong follow through skills and ability to proactively identify and solve problems; demonstrated initiative is imperative

Additional desirables requirements 

Interest in subarctic climate and mental health Knowledge of molecular chrono-medicine Strong technical skills with great attention to detail Proficiency in a programming language
