My research examines the social, cultural and ideological dimensions of discourse and is motivated by a theoretical interest in shedding light onto the connections between situated language use and broader contextual factors. I work from the assumption that social interaction is a key site in/through which political and cultural ideologies get enacted, reproduced and challenged. My research investigates multiple forms and media of social interaction as sites of social control and sites of resistance, orienting to a social semiotic theory of language and communication. My doctoral research and subsequent publications examined these theoretical concerns within the context of US community revitalization discourse. Since becoming a faculty member at NIE, I have pursued the above theoretical questions in two key substantive areas: the analysis of discourse in the education domain and pedagogical applications through critical approaches to English language education.
