Job title:
Professor of Multilingualism

Responsibilities:Treasurer of the University Council for General and Applied Linguistics.

Areas of interest

Jeanine is interested in a wide range of areas in the field of Multilingualism and Second Language Acquisition. Most recently she has worked on the relationship between cognitive control and different types of code-switching behaviour. She is also interested in measuring language dominance in bilinguals/heritage speakers and has published an edited volume on this topic with Cambridge.

Furthermore, she has published on motion event construal, formulaic language, vocabulary learning and teaching, lexical richness, and automated assessment of vocabulary in bilinguals and second language learners. She has also worked on language, literacy and mathematics development among learners with English as an Additional Language (EAL) in the UK and among multilingual children in India.
