About me

  • I´m a Postdoctoral researcher at Karolinska Institutet and a member of the
    social gerontology group at the Aging Research Center (ARC).
    I have a BA in Sociology from the University of Iceland, and an MSc in Public
    Health from Centre for Health Equity Studies (CHESS, KI/SU). I defended my
    PhD thesis Unequal tracks? Studies on work, retirement and health [1],
    attained at Karolinska Institutet, in May 2021.

  • My main fields of interest are in social stratification, social gerontology,
    health inequalities, life course studies, causal inference and
    quasi-experimental methodology.
    My research work focuses on retirement and socioeconomic position in relation
    to health in old age. The overall aim of the PhD project was to empirically
    study how retirement processes are influenced by health status, social
    position and gender in Sweden using nationally representative data sources,
    and in turn how the timing of the labour market exit influences health and
    functioning at old age. Postdoctoral research is a continuation of the PhD
    project, with focus on psychosocial working conditions, early retirement and
