UCL BiLingo


About Us

We are a group of UCL-based researchers working in different areas of bilingual/multilingual language development in children. We all recognise our responsibility as researchers to contribute effectively to society and our local community, and thus encourage a dialogue with the London wider community about bilingualism/multilingualism.

It is essential for us to establish strong links and work in partnership with Mainstream/International/Complementary Schools, educators, the healthcare sector, non-profit organisations, community groups and other key agencies interested in bilingualism/multilingualism in London.  Recent research has shown that bilinguals’ experience of dealing with two languages can have cognitive advantages in specific domains and that literacy skills and strategies learned in one language transfer to the other.

One of our key objectives is to bridge the gap between researchers and the wider London community by disseminating recent research findings, which highlight the cognitive, educational, and social advantages associated with the experience of acquiring two or more languages in childhood, including the importance of maintaining the child’s home language(s).

Froso Argyri    

Froso Argyri


Froso Argyri's (UCL Institute of Education, Centre for Applied Linguistics & Psychology and Language Sciences) research focuses on the language development of children who are exposed to more than one language from birth or later on.  She is investigating the role of various factors in bilingual/second language acquisition in children, e.g., How does age of first exposure to one or more languages affect language development?  What is the role of the amount and quality of input bilingual/multilingual children receive in different contexts?  She is also interested in the cognitive effects of bilingualism, the acquisition of literacy skills in two languages (biliteracy), the language development of bilingual children with developmental disorders, as well as in heritage/home language development and maintenance.  Froso is a mother of two trilingual children acquiring Greek, Icelandic and English.
