Bruce Derwing is Emeritus Professor of Linguistics at the University of Alberta, where he taught from 1968 through 1996. His early research focused on the philosophy of linguistics and child language, but most of his career has been devoted to the cross-linguistic experimental investigation of the psychological reality of phonological and morphological units, with a special interest in the role of orthographic knowledge on the perceived segmentation of speech. He has also had a long-standing pedagogical interest in the teaching of Russian phonetics and phonology to non-native learners.
