Marie is co-director of Centre for Research on Socio-Cultural Change. She researches diaspora and national media cultures comparatively, historically and ethnographically. Her interests cluster around South Asian and Middle Eastern diasporas, cultural transnationalism, and changing configurations of audiences and publics in relation to question of citizenship. Recent collaborative include: a large-scale study of the BBC World Service as a multi-diasporic institution; an exploration of the new politics of security via a collaborative ethnography of transnational news cultures in multi-ethnic British households in eight UK cities; a national survey with the BBC on the changing face of British humour, ethnic jokes and comedy. Marie was awarded an AHRC Public Policy Fellowship in 2011 to develop research on the interface between international broadcasting and social media, specifically in relation to the BBC Arabic Services.
