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. 

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

COMPARATIVE POPULISMS 

My main ongoing project (mainly with Cristóbal Rovira Kaltwasser) entails a cluster of
articles and (edited) books on populism and democracy, mostly with a (pan-)European and
(pan-)American focus. The underlying goal of these projects is to come to a broader
understanding of populism in general, and its ambivalent relationship to liberal
democracy in particular, by employing cross-national and cross-regional comparisons. 

'ECO-TERRORISM' AND STATE REPRESSION 

This ongoing project (partly with Sivan Hirsch-Hoefler) focuses on
'eco-terrorism' and the state responses to it and assesses the threat to
liberal democracy of both. The term is used to denote the radical animal rights and
environmentalist movement, which has been accussed of involvement in violent actions in
many democratic countries. Different sub-projects address the problematic terminology of
'eco-terrorism,' the activities and (lack of) organization of major groups
(like ALF and ELF), and the extent and explanations of state reponses (particularly in
the US). 

THE ISRAELI SETTLER MOVEMENT 

The main aim of this ongoing project (with Sivan Hirsch-Hoefler) is to explain the
continuing political success of the Israeli settler movement. Applying in particular
social movement theories, we hope to better understand what explains its enduring success
and what this teaches us about social movements in general. 

ISLAMOPHOBIA 

A new project investigates Islamophobia in contemporary western societies, in particular
Western Europe and North America. It aims to develop a comprehensive assessment of the
role of Islamophobia in contemporary western politics. Topics that are to be addressed
include: (i) what role does Islamophobia play in the (domestic and foreign) policies of
western states?; (ii) what are the effects of Islamophobia on western societies; (iii)
what effects does Islamophobia have on political alliances within and between western
states? 

C.O.M.P.S. 

I am involved in an ongoing research project in political methods, entitled
Conceptualization, Operationalization and Measurement in Political Science (COMPS). This
project is largely infrastructural, and is undertaken in collaboration with the IPSA/APSA
Concepts & Methods (C&M) group. In addition, it also includes original research
on these topics (notably with Andreas Schedler). 

OI! THE POLITICS 

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
rule". 

BLOGS/OP-EDS 

I regularly contribute to non-academic journals and newspapers. Most notably, I write for
Extremis Project, Open Democracy and the Washington Post (Monkey Cage). You can follow me
