About

My research activity is focused on ageing and dementia using population data from The HUNT Study.

I'm currently leading the planning of aging research and clinical examinatins for the 5th wave of The HUNT Study (HUNT5, 2028-30).

Current research projects involve dementia, frailty, sarcopenia, nutrition, oral health, multimorbidity, cancer and sexual health.

For the academic year 2024/25 I did a sabbatical as Visiting Associate Professor at Yale School of Medicine, supported by a scholarship from the Fulbright Program and funding from Central Norway Regional Health Authority.

During the 4th wave of HUNT, I was project manager for the HUNT4 70+ project. HUNT4 70+ included 9956 older adults, with blood samples, questionnaire and clinical assessments of cognitive function, balance, muscle strength, gait, nutrition and oral health.

Before coming to HUNT and NTNU I did a PhD in Iver Langmoen’s lab at Dept. of Neurosurgery and Institute for Surgical Research at Rikshospitalet, University of Oslo. I studied acute effects of hypoxia on mitochondria and calcium homeostasis in immature and mature neurons and glioblastoma stem cells.

As clinician I have experience as resident in neurosurgery, calls in neurology. Since 2013 I have been a family physician. I am partner at Sjøsia legekontor in Steinkjer and supervisor for younger pysicians. As Associate Professor in Family Medicine I teach medical students at NTNU. I was co-editor and authour of several chapters for the Norwegian text-book in Family Medicine "Allmennmedisin" (Hunskår) 4th edition.

My background from the laboratory and cell biology, and long-lasting fascination of the brain, have inspired population-based projects on dementia and bio-markers, finding exciting opportunities provided by the advanced HUNT Biobank and the comprehensive HUNT Databank.
