Associate Professor I teach courses primarily 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. Recent publications include articles in American Speech and Language Learning. Current projects include The Linguistic Diversity of German: Sociolinguistic and Structural Variation in Europe and the Diaspora (Oxford University Press), with Josh Brown, Michael Putnam, and Joseph Salmons; and editing The Oxford Handbook of the German Language, with Simon Pickl.
