Her recent research has focused on communication in NGO-sponsored HIV/AIDS prevention and awareness education in Tanzania, where she has investigated the discursive construction of local and global worldviews. In her book, English as a local language: Post-colonial identities and multilingual practices (Multilingual Matters), she has also explored the role of language and popular culture in HIV/AIDS awareness efforts in hip hop lyrics and in public health advertisements.
