Om mig

I am a researcher at the Institut des sciences sociales, University of Lausanne and at the Swedish Institute for Social Research (SOFI), Stockholm University. Before, I worked at Nuffield College, University of Oxford. I received my PhD in Political and Social Sciences from the European University Institute (EUI) in 2015.

My research aims at understanding the intergenerational transmission of advantage. For this purpose, I conduct both descriptive studies estimating differences in social mobility across countries, over time, and between groups within societies as well as causal studies that identify the effects of institutions on social mobility. A particular emphasis of my work is on socioeconomic differences in the impact of demographic factors, such as parental separation, and differences between siblings on children. Furthermore, my research explores which mechanisms underlie the intergenerational transmission of advantage, in particular the contribution of parenting to this process.
