His work addresses multilingualism from multiple perspectives, integrating linguistic, social, and cultural dimensions. His current projects include analyses of data from a Fulbright-supported study on second dialect acquisition among Ecuadorians living in Spain, as well as research documenting the linguistic, cultural, and social characteristics of bilingual regions in the U.S. South.
