Om mig

I am a researcher and Docent (Associate Professor) at SUDA (Stockholm University Demography Unit), CEK (Centre for Cultural Evolution), and IF (Institute for Future Studies), working on various aspects of intergenerational demography, economic demography, same-sex childbearing, and cultural evolution. Many of my research interests are about the demography of kinship and economic demography in contemporary and historical populations. Currently, I use linked register and parish data with micro-level data to examine demographic change from the mid 18th century until today. I am also working with researchers at the program for historical demography at Academica Sinicia in Taipei, Taiwan.

My research interests are often related to intergenerational demographic processes, but I have written papers on many areas of demography, including fertility, mortality, migration, same-sex demography, household composition, and union formation. I am also interested in cultural evolution, and in particular relationship between cultural evolution and demographic parameters.

Recent studies include; kinship and stratification, long-term consequences of intergenerational transmission of fertility, age differences in unions, cohort approaches to migration, and influences of family composition in childhood on various demographic outcomes. 

My Google Scholar page is available here and my CV can be found to the right.
