Personal profile

Personal information

Betty de Hart is a professor of transnational families and migration law at Vrije Universiteit. She conducts legal, empirical and historical research on the national, European and international rules that transnational families encounter, the views behind these rules as well as the impact on the everyday lives of transnational families. Such research will provide new insights into the meaning of nationality, citizenship and belonging.


Betty de Hart is the recipient of a 2017 European Research Council (ERC) Consolidator Grant to establish an independent research team and research program for her research project EUROMIX: Regulating Mixed Intimacies in Europe. The project answers the question of whether, how and why ‘mixed’ relationships are regulated in Europe, how ‘mixed’ couples respond to regulation and the role that law and lawyers play in the way in which thinking about “race” has developed in Europe.


In 2012, she published her book on dual citizenship, in Dutch: Een tweede paspoort. Dubbele nationaliteit in de Verenigde Staten, Duitsland en Nederland Amsterdam University Press, 2012). Earlier, in 2007, she received a Vidi-grant from the Netherlands Organisation for Scientific Research (NWO) for her research project 'Transnational families between Dutch and Islamic family law'.

In 2003, she completed her doctoral dissertation on citizen sponsors with a migrant partner and migration law, in Dutch: Onbezonnen vrouwen. Gemengde relaties in het nationaliteitsrecht en het vreemdelingenrecht (Aksant Amsterdam 2003).


Betty de Hart has participated in various international research projects, including projects focusing on dual citizenship, family reunification and nationality law in the fifteen 'old' Member States of the European Union.
