Jonas Johansson
Senior Researcher
Job description
I am a Senior Researcher employed at the Department of Community Medicine, UiT. I primarily work with epidemiological research data from the Tromsø Study and I lead the scientific committee for the upcoming Tromsø8 data collection wave planned to take place in 2025-2026. I also work with the RESTART project, a randomized controlled trial where we will investigate how a complex lifestyle intervention can improve and maintain the health status of older adults 60+. My background is in exercise physiology and I have a PhD in Public Health.
