David Block is ICREA Research Professor in Sociolinguistics in the Departament d’Humanitats at the Universitat Pompeu Fabra and member of the Grup de Recerca en Espais Interculturals, Llengües i Identitats (GREILI). From 2012 to 2019, he held the same post at the Universitat de Lleida and from 1996 to 2012 he worked at the Institute of Education, University of London (now University College London Institute of Education), where he was Professor of Languages in Education from 2008 to 2012. Over the past three decades, he has published books, articles and chapters on a variety of topics, including globalization, migration, multiculturalism, multilingualism, identity, narrative research and second language teaching and learning. His interests at present vary widely. First, he is interested in examining multimodal practices and phenomena of all kinds (including political discourses, social movements, multiculturalism and bi/multilingualism) drawing on scholarship in political economy, sociology, anthropology and geography. Over the past ten years he has focused on the dominant form of capitalism in the early 21st century (what some would call ‘neoliberalism’) and inequality and social class divisions as key collateral effects. His most recent work deals with two very different aspects of contemporary society: on the one hand, he has focused on ‘post-truth’ and related concepts and the critical analysis of political discourses; on the other hand, he has focused on the internationalization of higher education worldwide as part of the broader neoliberalization of societies. He is co-editor, with Deborah Cameron, of Globalization and Language Teaching (Routledge, 2002) and co-author, with John Gray and Marnie Holborow, of Neoliberalism and Applied Linguistics (Routledge, 2012). He is sole author of The Social Turn in Second Language Acquisition (Edinburgh University Press, 2003); Multilingual Identities in a Global City: London Stories (Palgrave, 2006); and Second Language Identities (Continuum, 2007; re-issued in 2014 as a ‘Bloomsbury Classic in Linguistics’); Social Class and Applied Linguistics (Routledge, 2014), Political Economy and Sociolinguistics: Neoliberalism, Inequality and Social class (Bloomsbury, 2018; shortlisted for the 2019 BAAL Book Prize) and Post-Truth and Political Discourse (Palgrave Macmillan, 2019). He is currently writing a book entitled Innovations and Challenges in Identity Research for Routledge, and co-editing, with Sarah Khan, The Secret Life of English-medium Instruction, also for Routledge. He is a member of the Academy of the Social Sciences (UK); Visiting Professor at University College London Institute of Education; editor of the book series Language, Society and Political Economy (Routledge); and Associate Editor of the journal Applied Linguistics Review.
