He also lectured in the linguistics department at Rhodes University in Grahamstown. His chief research focus is the sociophonetics of South African English, focusing both on this variety's genesis and historical development as well as its current internal variation and change. He has recently expanded his research interests to include current phonetic developments in Afrikaans, along with bilingualism, linguistic and literary style, South African literature, heteroglossia, and anything to do with the Russian theorist, Mikhael Bakhtin. His mentor is Patrice Beddor, John C. Catford Collegiate Professor of Linguistics.
