The research group includes university employees and other researchers affiliated with the Children and Youth Department and the Child and Adolescent Psychiatric Department (BUK, UNN), as well as those with pure university positions linked to the Pediatric Research Laboratory at the Faculty of Health Science of the University of Tromsø.

The strategy of the research group is based on the research strategy of the Faculty of Health Sciences, University of Tromsø, and UNN/Northern Norway Regional Health Authority.

1. Primary Goal (long-term)

Generate new knowledge about the somatic and mental health and diseases of children and youth to better prevent and treat them.

2. Annual Sub-Goals

  • Complete 2 new doctoral degrees
  • Secure external funding for 2 new PhD candidates/postdoctoral researchers
  • Recruit 1 new master's student and 1 new medical research student

Research Focus

We will research areas where, in collaboration with others, we excel, aiming to produce publishable results in reputable journals (neonatology, infections, oncology, child and adolescent psychiatry, allergy, rheumatology).

In other fields, we will seek external expertise (fetal physiology, obesity, pain, epidemiology) to conduct quality research that stimulates clinical activities.

Research Fields BUA and BUPA

  • Premature Intervention Project
  • Infections (biofilm, staphylococci, microbiome)
  • Cancer (neuroblastoma, clinical cancer research)
  • Rheumatology
  • Mental disorders
Most projects involve collaboration with other groups on-site and internationally

Fit futures

Epidemiological and clinical examination of all 1st-year students in high school in Tromsø. This has been repeated for 3rd graders, resulting in numerous sub-projects, including overweight, stomach pain, iron metabolism, and fish allergy.


There is academic diversity in the research group, including representatives from various backgrounds:

  • Natural scientist/engineer, physician
  • Psychologist, nurse
  • Research line student, master's student
  • PhD candidate
  • Postdoctoral researcher/researcher/associate professor
  • Professor


  • Funding sources include internal funds from BUK, UNN, IKM, UiT, competitive grants from UNN/UiT, allocations from Helse Nord (somatic, mental, telemedical), grants from DNK, NFR, others, and EU funding.
