The department is a lively community that is recognised internationally as one of the top centres for research and teaching in development studies.
Mathias is interested in the political economy of migration (how do migration policies come about?) and the role of migration policies in shaping international migration flows (how do the various types of migration policy instruments influence migration flows?). Currently, his research focus is on the qualitative assessment of the effects and the effectiveness of migration policies as well as the quantification of these policy effects.
Mathias has a PhD in Political Economy (University of Freiburg, Germany) and a Diploma in Economics (University of Konstanz, Germany). In his PhD thesis, published in 2009 with Palgrave Macmillan, he explores the determinants of forced migration and its political implications from an economic perspective. He describes the distribution of burdens from forced migration across countries, and analyzes the strategic interaction of national refugee policies to control refugee flows.
Prior to joining the International Migration Institute (IMI) in April 2010, he held a lecturer position at the University of Freiburg (Centre for Renewable Energy) and a position as economic advisor with GTZ (the German Development Cooperation Agency).
