I am an Associate Professor in the School of Public and International Affairs at the
University of Georgia. I was born in the Netherlands, where I received my MA and PhD at
Leiden University. Having held tenure-related positions at Central European University
(Budapest, Hungary), the University of Edinburgh (UK), and the University of Antwerp
(Belgium), I moved to the US in 2008, where I have been a Visiting Professor at the
University of Oregon (2008-9), a Visiting Fellow at the University of Notre Dame
(2009-10), and Nancy Schaenen Visiting Scholar (2010-11) and Hampton and Esther Boswell
Distinguished University Professor of Political Science (2011-12) at DePauw University. 

My primary research agenda is build around the crucial question: How can liberal
democracies defend themselves against extremist challenges without undermining their own
core values? Building upon an earlier developed typology of extremist challenges to
liberal democracy, which distinguishes between the aims and means of the challengers, I
aim to answer this question from both an empirical and normative perspective, looking for
as well as developing 'best practices.' 

My work is primarily conceptual and empirical in nature. After an initial focus on
Western Europe, I have expanded my primary focus to both Eastern and Western Europe and
developed a secondary interest in North and South America as well as Israel. The bulk of
my research has been within the field of extremism and democracy, particularly populist
radical right parties. Secondary interests include civil society, conceptualization,
democratization, Euroskepticism, political parties, and political ideologies. 

From 2013 till 2015 I was the editor of the Working Paper series on Political Concepts
and on Political Methodology of the IPSA Committee on Concepts and Methods. As of Summer
2015 I am co-editor of the European Journal of Political Research (EJPR), the flagship
journal of the European Consortium of Political Research (ECPR). 

I am currently working (on and off) on a diverse set of research projects in comparative
politics and political methodology. 


As the (provisional)end of this long-term project Cristóbal Rovira Kaltwasser) and I are
writing "Populism: A Very Short Introduction" for Oxford University Press. We
hope to finish the book manuscript in Summer 2015 and have the book out in print in 2016. 


This ongoing project with Sivan Hirsch-Hoefler should result in a book, provisionally
entitled "The Israeli Settler Movement: Assessing and Explaining Social Movement
Success", which is under contract with Cambridge University Press. Applying a broad
theoretical framework, in particular social movement theories, we hope to better
understand what explains the Israeli Settler Movement's enduring success and try to
learn lessons about social movements in general. 


This ongoing project critically analyzes how western democracies deal with (perceived)
political threats and assesses whether the cure (state repression) is better or worse
than the disease (the threat). I am focusing on state responses in North America and
Europe to a broad range of (perceived) threats, including so-called anti-globalization
movements, eco-terrorism, far right parties, and international terrorism. 


My side project, on which I work on and off, is a monograph that analyzes the main
political positions expressed in Oi! music. The book will focus mainly on the political
views of British Oi acts in the explosive period of the late 1970s and 1980s with
political events like the miners strike and Margaret Thatcher's "iron


I regularly contribute to non-academic journals and newspapers. I have written for
Guardian, Open Democracy, Reuters, and the Washington Post (Monkey Cage). 

I am also (very) active on Twitter. You can follow me at @casmudde
