Her research and teaching interests lie at the intersection of urban sociology, immigration, race, and ethnicity. Specifically, she examines how black immigrants understand their own ethnically-specific identities in the United States. This shift in perspective explores how black immigrants produce ethnic boundaries that extend far beyond ethnic conflict with African Americans and incorporates dimensions of cultural performativity, nationality, political and class ideologies, transnationalism, and citizenship status.
