I am an economic and social historian with a special interest in historical demography, family and gender history. I have published on infant and childhood mortality, female labour participation, adoption practices, social epidemiology, family and care systems, children and violence, and on the link between religion, health and (cause specific) mortality. Focus lies on the nineteenth and twentieth centuries.
Affiliated and tenured Assistant Professor of Economic and Social History at Leiden University and affiliated member of the Radboud Group for Historical Demography and Family History in Nijmegen. I serve as president of the International Committee for Historical Demography/Commission Internationale de Démographie Historique.
