Elin Thordardottir, a certified Speech-Language Pathologist – Audiologist is a professor at McGill University in Montreal, Quebec, Canada, and an adjunct professor at the University of Iceland. She received her clinical and research training at the University of Wisconsin-Madison (M.S and Ph.D.). On the faculty of the McGill School of Communication Sciences and Disorders at McGill since 1998, she teaches courses on developmental language disorder (DLD) in monolingual and bilingual children, its nature, underlying causes, assessment and intervention. She runs research labs in Montreal and in Iceland, and lectures regularly at the University of Iceland. Her research focuses on the normal language acquisition and language disorders in children learning one or more languages, the assessment of bilingual and multilingual children and intervention efficacy. This work has a strong cross-linguistic focus, comparing languages that differ in structure, and also a strong focus on environmental factors, notably comparing the very distinct multilingual environments of Montreal and Iceland. Elin is the author of several language assessment tools in Icelandic and French. She has worked closely with school boards and impacted policy making. Recently, Elin was vice-chair of a European multi-national research network focusing on the treatment of oral language impairment across countries of Europe and beyond (Cost Action IS1406). She is frequently invited to give research talks and continuing education workshops across the world, recently in Iceland, Belgium, Italy, Portugal, Switzerland and Austria.
