This episode of Conversations with IRiS offers insights into the experiences of Brazilians in London and questions assumptions on 'community' and its boundaries. Nando Sigona speaks to Angelo Martins Jr, the author of 'Moving difference' an ethnographic exploration of how race, class and gender constructions travel with migrants and shape their migratory plans and trajectories as well as their experiences in the countries of residence and origin. Angelo also reflects on his work with sub-Saharan African migrants in Europe and Brazil and how his positionality plays a role in how he interact and engage with research participants. Dr Angelo Martins Junior is Assistant Professor of Sociology at the University of Birmingham, UK.
