Do has been involved with CLIL research since becoming a languages teacher (French and Russian) in challenging secondary schools in the UK. She held a Sixth Century Chair in Leaning Innovation at the University of Aberdeen 2008-2017 where she was Dean of the School of Education. Prior to her move to Scotland, she was at the University of Nottingham where along with her colleague Philip Hood and David Marsh wrote the 2010 Cambridge University Book on Content and Language Integrated Learning, introduced the first initial teacher education programme for CLIL in the UK, carried out extensive European research into CLIL classrooms and published her work extensively. Her own PhD is in classroom talk in CLIL classes.
More recently, her research has focussed on PluriLiteracies and new models for bilingual learning as a member of the Graz Group. Do has published books, chapters and articles in a range of journals including International Journal of Bilingual Education and Bilingualism. She works with teachers globally and seeks always to enable all learners to engage in deeper learning using more than one language and to be supported in languaging their learning to feel a sense of achievement and success. She has just taken up a new post at the University of Edinburgh where she is Chair of Languages and Classroom Education bringing together MFL, TESOL and EAL.
