Social Sciences


I am a social worker, senior lecturer in social work and an associate professor (Docent) of sociology.

My current research interests relate to suicide, life course studies, over-indebtedness and knowledge-based practice in social work. I defended my PhD thesis, entitled “Childhood Social Exclusion and Suicidal Behavior in Adolescence and Young Adulthood”, in 2014.
