Is Senior Researcher and Lecturer at the Department of Geography, Planning and International Development Studies, where she heads the Transnational Migrations Research Program. Between 2001 and 2007 she was awarded a 5-year grant from the Netherlands Organization for Scientific Research (NWO), to head an inter-university and interdisciplinary research program called Ghana TransNet, on the effects of Ghanaian migrant transnational networks on institutions that govern economic behavior in migrant neighborhoods in the Netherlands and in migrants' regions of origin. The program studied the effects of transnational linkages between migrants and their home regions on the development of these regions, on housing and business activities and on the provision of social security. At the same time it looked at the impact these linkages have on the livelihood of Ghanaian migrants in the Netherlands, their integration and their engagement in transnational activities.
Mazzucato is currently one of the three Scientific Coordinators of a European 7th Framework research program on Migrations between Africa and Europe (MAFE) lasting from 2007 to 2012, in which a large-scale matched sample survey will be conducted amongst migrant households in Senegal, Congo and Ghana and their respective migrants in France, Spain, Italy, the Netherlands, Belgium and the UK. The aim of the program is to trace the patterns of African migrations to and from Europe, identify the determinants of these migratory patterns and study the socio-economic effects of such migrations at the individual, family and societal levels.
