Helga de Valk


I am theme group leader Migration and Migrants at the Netherlands Interdisciplinary Demographic Institute (NIDI, the Hague) and professor at Interface Demography Free University Brussels (VUB, Belgium). At both institutes I collaborate with a team of researchers in different stages of their academic career. My main research interests are related to a wide range of topics from migration and migrant characteristics to the transition to adulthood of immigrant youth, educational inequality, union and family formation, and intergenerational relationships in immigrant families. My work covers both non-European migrants as well as European mobility and migrant populations. This is reflected in my ongoing projects including the ERC starting grant project “Families of migrant origin: a life course perspective” (Familife) and the Norface funded “European welfare states in times of mobility” (MobileWelfare) project. Furthermore I am the editor in chief of the European Journal of Population.

Kim Caarls

I‘m a postdoctoral researcher at the Netherlands Interdisciplinary Demographic Institute (NIDI). For my PhD dissertation, I investigated how Ghanaian families form, transform and possibly dissolve in the context of international migration. I have ample experience with complex survey designs and advanced statistical methods. At NIDI, I continue to study the effects of international migration on family life with the FaMiLife project. In line with this project, I emphasize the need for an origin and destination perspective in order to fully understand the functioning of family life across borders.

Tanya Eremenko

I’m a demographer interested in the topics of family formation and international migration and the intersection between these two processes. My PhD dissertation focused on migrant families in France and the role of demographic, socio-economic and legal factors in shaping their migration trajectories and experiences. Currently I’m involved with the projects « Families of Migrant Origin – A life Course Perspective » at NIDI and « Temporary versus Permanent Migration » at INED.


I hold a Bachelor Degree in Interdisciplinary Social Sciences and completed a Research Master in Migration, Ethnic Relations and Multiculturalism at the Utrecht University’s Graduate School. Currently, I’m working on my PhD dissertation at the Netherlands Interdisciplinary Demographic Institute (NIDI), focusing on family relations in migrant and non-migrant families. My research interests particularly include parent-child relationships in adulthood, transnational families and acculturation. For analyses, I use both quantitative and qualitative data.

Ilse Rooyackers

I received my masters degree in sociology from Tilburg University in 2011. Since then, I work at the Netherlands Interdisciplinary Demographic Institute (NIDI) as a PhD student. My dissertation research is focused on family-life courses of new groups of immigrants as well as the second generation of more established immigrant groups in Europe. The analyses performed are based on quantitative research methods, such as event history and sequence analysis.
