The study group investigates the historical and conceptual layering processes that both ingrained racial categories into the government of human mobility and continuously reworked them into putatively race-free migration and refugee systems. Members of the study group critically unpack the colonial assumptions underpinning the idea of equal nation-states and citizenship rights that are central to the global organisation of mobility and labour. Also, reflexively aware of entrenched theoretical biases, they study the coloniality present across ongoing methods and practices when researching migration and borders, and engaging with post/decolonial approaches to mobility justice and knowledge production.
