Professor Andrew Chadwick

Andrew Chadwick (BSocSc Birmingham, MSc London School of Economics, PhD London School of Economics, FRSA, FAcSS) is Professor of Political Communication and Director of the Online Civic Culture Centre (O3C) in the Department of Communication and Media. He teaches courses on digital media and society, online influence, and data, power, and democracy.

His research explores how the internet and internet and digital media are implicated in social and political power in four broad areas: political mobilisation, political engagement, deception and dis/misinformation, and news and journalism. He invented the concepts of the “hybrid media system,” “hybrid media events,” “organizational hybridity," and the “ontology of hybridity” and introduced them into social science research, where they have become influential in a wide range of fields including political communication, journalism studies, social movement studies, social media analysis, public opinion research, algorithm studies, party and election campaign research, communication theory, social theory, dis-/misinformation research, media audience/reception studies, and analyses of populism.

His work takes a broadly interdisciplinary, sociotechnical, and social scientific approach inspired by some key concepts and methods from communication, political science, sociology, psychology, and science and technology studies.

Andrew’s books and journal articles have won multiple international awards from the American Sociological Association, the International Communication Association, and the American Political Science Association. In addition, The Hybrid Media System: Politics and Power (Oxford University Press, 2013; Second Edition, 2017) won the International Journal of Press/Politics Best Book Award (2016), which recognises an outstanding book published in the previous ten years.

Among other projects, he is currently working on his next book (working title Social Media and the Future of Democracy), which will be published by Oxford University Press. Since 2016 he has mostly been writing about online disinformation, misinformation, deception, distrust, and other online harms. This has involved establishing a new research centre and doctoral programme at 含羞草视频, the Online Civic Culture Centre (O3C), for which he gained funding and founded in February 2018, and the Everyday Misinformation Project, which focuses on the everyday sharing of misinformation on personal messaging platforms and is funded by a large grant from the Leverhulme Trust. From 2020 to 2023 he was a prominent researcher in the multidisciplinary Oxford Coronavirus Explanations, Attitudes, and Narratives Project on misinformation and Covid-19 vaccine hesitancy, to which he brought expertise in online social endorsement. This resulted in an award-winning journal article he led that informed part of the UK government’s response to vaccine disinformation during the Covid vaccine rollout.

Andrew is the founding series editor of Oxford University Press’ book series Oxford Studies in Digital Politics, which launched in 2010 and currently features 46 books. Books in the series have received 25 major international scholarly book awards to date. He also serves on the editorial boards of several journals (all Q1) including Journal of Communication, New Media & Society, Political Communication, Communication Theory, Social Media + Society, and International Journal of Press/Politics,

A Fellow of the Academy of Social Sciences, a Fellow of the RSA, Andrew is listed in the Stanford University/Elsevier Top 2% of Scientists Worldwide, 1960-2020. In 2019 he became an adviser (unpaid) to Clean up the Internet, an independent organisation tackling the degradation of online discourse and its implications for democracy. He has served as an adviser to the Department of Digital, Media, Culture and Sport (DCMS) (Counter-Disinformation Policy Forum, 2020-22) and the DCMS/Department for Business, Energy and Industrial Strategy (BEIS) Digital Markets Research Working Group.

Media engagement includes BBC Radio Four’s Thinking Allowed, The Moral Maze, The World at One, and Sky News. He has written for the British and U.S. press, including The Independent, the Washington Post, and The Conversation. News organizations in the UK, Finland, Italy, Japan, Norway, Portugal, and Spain, among other countries, have covered his research, including in outlets such as The Times, BBC News, the Washington Post, ITV News, The Wall Street Journal, Newsweek, CNN, the Independent, Bloomberg News, the Telegraph, the New Scientist, First Draft, Campaign, New Statesman, and Stylist.

Andrew has given keynote speeches in in Canada, Estonia, Finland, Italy, Norway, Portugal, Spain, and the United Kingdom, and invited lectures in Austria, Canada, Italy, Norway, Spain, the United States, at many universities across Britain, and at other public institutions including the Parliament of Canada, the UK Parliament, the UK Cabinet Office, the US Congressional Research Service, the RSA, the US Embassy in London, the Royal Institute of International Affairs (Chatham House), Gresham College, the Cheltenham Science Festival, the Institute of Historical Research, the European Parliament Information Office, the UK Labour Party, and Policy Network.
