Dr. Gigi Luk’s research on the cognitive and neural consequences of bilingualism extends across the lifespan. She leads a research program that examines how diverse language experiences shape development and learning. Using neuroimaging and behavioral methods, Dr. Luk studies bilingualism as an interactional experience that shapes cognition. In addition to investigating the science of bilingualism, Dr. Luk has examined how to harness scientific findings on bilingualism to improve educational experiences for children from diverse language backgrounds. In particular, she has established a research program investigating: (1) effective ways to examine bilingualism and learning; (2) how bilingualism and executive functions interact to influence literacy outcomes; and (3) brain mechanisms underlying learning new information in children and adults. Dr. Luk obtained her Ph.D. in cognitive psychology from York University, Canada in 2008. She then completed a postdoctoral fellowship at the Rotman Research Institute at the Baycrest Center before joining the Harvard Graduate School of Education in 2011. In January 2019, she joined the Department of Educational and Counselling Psychology at McGill.
