"(1) Language contact phenomena. Major concern: grammatical consequences of bilingualism for languages, especially codeswitching and convergence, but also attrition, pidgin and creole development (Matrix Language Frame model and model of Matrix Language Turnover).

(4) Discourse analysis and stylistics. Study of the structure and content of both literary texts and natural conversation.
(5) Study of African languages, particularly with regard to multilingualism and related issues. Specialization: Swahili and the Bantu group of languages in general."
