I am an educational linguist interested in cultural diversity, inclusion, multilingualism and school achievement. Specializing in sociolinguistics, my research seeks to shed light on the linguistic, cultural, social, and intercultural outcomes of language contact. I published extensively on language maintenance and shift, acculturation orientations of immigrants, bilingualism, and school achievement as well as multilingualism. My recent research focuses on diversity and social inclusion from a policy perspective. I am particularly interested in the formulation and enactment of multilingual policies in the European context. I am an advocate of unity in diversity principle. Together with several PhD candidates, I investigate the links between parents, schools, language policies, multilingual children and the teachers. Family language policy among parents in different communities and teachers' attitudes towards multilingualism is my current research project.
