I am professor of sociology of education at the University of Iceland (since January 2023). I also hold a part-time position at Aarhus University. My research focuses on questions related to inequalities in educational attainment. I am particularly interested in educational transitions - such as the transition from upper secondary education to higher education or the transition from compulsory school to the subsequent schooling alternatives. In much of my research I have emphasized the importance of horizontal stratification in education (such as field of study choices or the choice of universities vs. university colleges). I am currently principal investigator for two major research projects: "EDUCHANGE, Changing Inequality at Educational Transitions" (ERC consolidator grant) and "Reducing Inequality in Access to Higher Education" (funded by the Independent Research Fund Denmark).
