I teach courses in sociolinguistics and historical linguistics, working primarily within the Germanic family of languages. My research seeks to better understand the social factors and typological tendencies affecting language change; and the social, economic and community factors that affect language shift, particularly in heritage communities.
A large part of my research is focused on heritage languages, or: linguistic communities of bilingual speakers whose mother tongue differs from the language of the society at large. I study both the linguistic effects of bilingualism in these contact varieties, as well as the sociological factors affecting language shift. Additionally, I work on diachronic change in Germanic, including the development and progression of complementizer agreement as a linguistic cycle; and language contact in early Germanic.
