GREIP (Research group for Education, Interaction and Plurilingualism) has a nucleus of expert researchers in the area of plurilingual interactions in education contexts. We work with experts across the globe and seek to advance knowledge about education in the 21st century. We also routinely collaborate with major stakeholders such as primary and secondary educators, administrators and policy-makers. We have been recognized as a consolidated quality research group by the Catalan Government since 2005.
