Tanja Bueltmann is a historian of migration and diaspora. Her research focuses on associational culture in immigrant communities and how immigrants use associations to facilitate collective action. This includes work on EU citizens’ groups in the context of Brexit, which has also seen Tanja comment on wider issues to do with immigration and citizens’ rights. Now a dual German-British national, Tanja has also been a campaigner for citizens’ rights. In her free time Tanja writes, together with two friends, the German fashion, lifetstyle and travel blog Stylerebelles for women over 40.
