My research centers on  the role of interaction in instructed language learning, among children and among adults, through socio-cognitive perspectives:

1. Peer interaction - how does it complement the role of the teacher?

2. Learner engagement in language classrooms - cognitive, social and emotional - how can we describe it? how can we foster it?

3. The contribution of individual differences in learning through oral interaction (e.g. working memory, language aptitude, motivation, learning preferences)

4.  The role of noticing, the place of corrective feedback, and of learner's output in language development.

5. Task based interaction - how does it work in foreign language settings?
