Agnes Bolonyai is an Assistant Professor in the Department of English at North Carolina State University. Her research and teaching interests are in both the structural and social aspects of bilingual language use, including code-switching, language attrition and maintenance, and the relationship between language and identity in bilingual contact situations. Her main research concern has been the development of models for explaining and predicting the effects of language contact and attrition at the morphosyntactic level. She has published articles on morphosyntactic changes in Hungarian as spoken by Hungarian-English bilingual children. Working within a lexically-based approach, she examines whether lexico-semantic and syntactic features are equally vulnerable in the production of case morphemes, preverbs, definiteness agreement, and possessive agreement in the children's Hungarian. Her research also includes the sociopragmatic aspects of bilingual language use. She co-authored an article with Carol Myers-Scotton, in which they apply rational actor models to code-switching. This approach focuses on individuals as rational social actors who make linguistic choices to optimize outcomes in a given interaction. Agnes's most recent research interest centers around issues of language choice, gender, and power, with particular emphasis on the linguistic construction of identity in bilingual girls' talk.
