About
I am a Senior Lecturer in Physical Education and Sports at OsloMet. My main academic interests are strength training and exercise science, physical activity, public health and life skills, sport psychology, and outdoor education/friluftsliv. I also work with physical education pedagogy and the physical and motor development of children and adolescents.
I hold a master’s degree in sport psychology from the Norwegian School of Sport Sciences, where my academic background also includes exercise science, coaching, and outdoor education. In addition, I have completed a two-year education programme in cognitive sport psychology, offered by the Norwegian Association for Cognitive Behavioral Therapy in collaboration with Olympiatoppen.
My research and development work includes physical activity, exercise and health among children and adolescents, strength training, quality of life, as well as the content and development of physical education. I also work with outdoor education and friluftsliv in schools and teacher education, including issues related to teaching, and the professional development of student teachers. Collaboration with schools, teachers, and other partners in professional practice is central to several of my projects.
I have teaching experience from both primary and secondary education and have worked in higher education since 2005.
