Field of work

I have been working at The Western Norway University of Applied Sciences (HVL), Faculty of Education, Arts and Sports, Department of Sports, Food and Natural Sciences, Campus Sogndal (formerly The Sogn og Fjordane University College, Faculty of Teacher Education and Sports, Institute for Sports) since 2008, since 2018 as Professor in Sport Science. I serve as the head of the research group Physical Activity and Public Health at HVL. My main research interests are in the fields of physical activity, physical fitness and health, physical activity in children and youth, physical activity in preschool and school, measurement of physical activity and physical fitness, accelerometers, risk assessment and risk management in outdoor activities and sea kayaking, sea kayak teaching and leadership. I lead two large-scale research- and development projects in kindergartens, the Active Learning Norwegian Preschool(er)s (ACTNOW) study and the Move-play-explore in early childhood education (MoveEarly) study.
