Before joining IES Christof Roos worked as research associate at University of Bremen (2007-2014) where he received his PhD in 2012. At Bremen International Graduate School for Social Sciences and the Collaborative Research Centre “Transformations of the State” he researched EU integration in Justice and Home Affairs. His focus is on EU immigration politics as well as single market issues such as freedom of movement, Schengen cooperation, and the common European asylum system. In 2013 he published his PhD Cracks in the Walls of Fortress Europe? The EU and Immigration Policies with Palgrave Macmillan. As a member of the interdisciplinary research project “From Containers to Open States. Border Regime Change and the Mobility of Persons” he was co-author of the project monograph Liberal States and the Freedom of Movement. Selective Borders, Unequal Mobility. He studied political science at Free University Berlin (2000-2006) and at York University Toronto (2003-2004). Questions of in-and exclusion and the right to membership and community are core to his studies. He teaches in the EuroMaster program of IES the course "Diversity Politics in Europe" and gives lectures on EU migration, asylum, and border policies at the Collège of Europe (Bruges). 

Outside of academia Christof Roos worked for the European Commission’s DG Joint Research Centre in Ispra (Italy). There he contributed to a study on emigration from West African countries (2006-2007). In 2013 and 2014 he worked on the European strategy on Roma Inclusion and on the European Smart Cities and Communities Initiative in the European Affairs Department of the Senate Chancellery of the city of Berlin.
