After obtaining a Ph. D. in Cognitive Psychology from York University in Toronto, Canada, she completed a postdoctoral fellowship at the Rotman Research Institute at the Baycrest Center in Toronto. Her research on the cognitive consequences of bilingualism extends across the lifespan. These cognitive consequences include literacy acquisition in children and executive functions in young and older adults. The main research finding is that bilingualism, as a language experience, results in some cognitive advantages and linguistic limitations at different developmental stages. For children in particular, these bilingual consequences entail cognitive and educational implications. Gigi Luk’s current research has focused on how dimensions defining bilingualism is construed in education.
