I finished my undergraduate degree in social sciences at Umeå University in 1970 and received my doctoral degree in sociology at Umeå University in 1975. I was a visiting scholar at Harvard University, Massachusetts, USA, and at University of Wisconsin, Madison, USA. Between 1986-1987 I was a visting fellow at the University of New South Wales, Sydney, Australien.
Between 1984-1988 I was an associate professor of social policy at the research council (DSF). During the years 1989-1999 I was a professor of sociology and social policy at Umeå University and in 1991-1992 a visiting professor at York University, Toronto, Canada.
During 1999-2007 I was a professor of occupational health at the National Institute for Working Life and an editor of the journal Arbete & Hälsa. Since 2003 I am a member of the regional research ethics board in Stockholm.
In May 2008 I was appointed professor of occupational health at the Karolinska Institutet and became a professor emeritus in 2015.
I am primarily doing research on social security and particularly on sickness absence. I have been concerned with causes and effects of sickness absence for the individual, for the work organization and for the society.
