Katherine Rehner

Professor, Linguistics
Language Studies

Graduate Appointment: Graduate Program in Language & Literacies Education, OISE

Katherine was born and raised in Toronto and has always been interested in why speakers say things the way they do, particularly in a second language. This interest in the nature of authentic oral discourse led her to the field of educational sociolinguistics, where she studies the development of sociolinguistic competence by first and second language speakers of French. Katherine enjoys dancing, music, and spending time with her family.
