Overview

NWO-VENI “The more the merrier? The role of step-grandparens in complex family networks”

  • University of Groningen, The Netherlands
  • Interuniversity Center for Social Science Theory and Methodology (ICS)

In the 1990s, the Netherlands experienced a peak in divorces. Now, 30 years later, divorced parents have often found new partners, and their adult children have established their own families. As a result, families can now consist of four biological grandparents and additional step-grandparents, potentially resulting in “eight-grandparent families”. By utilizing registers that document the kinship networks of the Dutch population, it is examined to what extent having step-grandparents can be a benefit or a burden for the younger generations. Additionally, new data is collected about step-grandparent relationships to understand under what conditions relationships with step-grandparents can thrive.

DFG-Walter Benjamin “Changes in the family network after parental divorce”

  • University of Cologne, Germany
  • Netherlands Interdisciplinary Demographic Institute (NIDI)

This research project was funded by Walter Benjamin funding of the German Research Foundation (DFG, reference: 502057823). As a POPNET fellow, I analyzed complex kinship structures using the family layer of the Dutch population-scale social network.

  • Netherlands Interdisciplinary Demographic Institute (NIDI)

2022-2023: NetResilience studies social networks, fertility and well-being in aging populations. I studied how contact between adult children and their parents is associated with adult children’s entry into parenthood, and whether this varies by level of education and gender. The paper is not published yet.

Postdoc project “CH-X”

  •  Swiss Centre of Expertise in Life Course Research (LIVES)
  •  University of Geneva, Switzerland

2020-2022: I have been working on a project about the personal networks of young adults in Switzerland. The aim of this project was to study which social capital matters for young adults’ educational attainment and their entrance to the labour market. Personal network data have been collected among more than 10,000 young adults and I was in charge of checking and cleaning the incoming 2020 data.

NWO-Talent Grant “The ripple effect in family networks. Relational structures and well-being in divorced and non-divorced families”

  • PhD research
  • University of Groningen, the Netherlands
  • Interuniversity Center for Social Science Theory and Methodology (ICS)

2015-2019: Why do some families fare better than others after parental divorce in terms of relationships quality and family well-being? Parental divorce not only affects the nuclear family, i.e., parents and children, but also affects extended family members, i.e., grandparents and aunts/uncles, and their relationships with the nuclear family. At the same time, extended family members can be an important source of support for nuclear family members after parental divorce. My thesis contains a number of studies on family network data from datasets collected by other researchers, as well as the first study on Lifelines Family Ties for which we collected multi-actor family network data among children, parents, grandparents, aunts/uncles and potential stepfamily members. My PhD research was funded with a talent grant from the Dutch Research Council (NWO, reference: 406-15-191
