Andreu Casas is a Lecturer in Political Communication at Royal Holloway University of London in the Department of Politics, International Relations and Philosophy, and a Faculty Associate in the Center for Social Media and Politics at New York University. He received his PhD in Political Science from the University of Washington . Before joining Royal Holloway, he was an assistant professor at VU Amsterdam, and a Moore Sloan research fellow in the Center for Data Science and Center for Social Media and Politics at the New York University; and a research fellow at the Amsterdam School of Communication Research.

Dr. Casas is a computational political scientist working on political communication, public policy, legislative politics, and computational methods. His substantive research focuses on building a better understanding of the policymaking process, broadly speaking, in the current digital society. His research in political communication and public policy looks at how social media has shaped collective action dynamics; how social movements, interest groups, political parties, as well as the public, use public communications to influence the political agenda; the role of (social) media in increasing/ameliorating polarization; and the regulation of political speech by social media companies. His research on legislative politics looks at the conditions under which individual legislators and legislative groups influence policy through less prominent (e.g. amendments) and more informal (e.g. bundling legislation) mechanisms. In addition, in all his research Dr. Casas develops and/or applies novel computational methods (text-as-data and images-as-data) that allow him to unlock important (classic and new) research questions that would not be able to address otherwise.

Dr. Casas' work as been published in top academic outlets such as Science Advances, American Political Science Review, American Journal of Political Science, Journal of Politics, Annual Review of Political Science, Political Analysis, etc., and a book with Cambridge University Press. His research has been funded by many organisations, such as the European Research Council, NWO, NSF, Facebook, and La Caixa Foundation. Currently, he is the PI of a NWO-VENI grant exploring political biases in the moderation of political content on social media platforms (or the lack therof), and the PI of a work package in the WHAT-IF project funded by Horizon Europe.
