I am a Principal Research Officer at the National Research Council of Canada and an Adjunct Professor at the University of Ottawa. I obtained my PhD in 1988 from the University of Toronto and joined the NRC in 1989. My recent work focuses on machine learning applied to natural language. I am the author or co-author of more than eighty publications. In the past, I have been an Editor of Canadian Artificial Intelligence magazine, an Editorial Board Member, Associate Editor, and Advisory Board Member of the Journal of Artificial Intelligence Research, and an Editorial Board Member of the journal Computational Linguistics. I was involved in initiating the Wiki of the Association for Computational Linguistics in 2006 and continue to play an active role in its maintenance. My paper Mining the Web for Synonyms won the ECML PKDD 10 Years Award in 2011.
