List of publications


My name is Diego Garzia. I hold a PhD in ‘Comparative and European Politics’ from the University of Siena. Previously, I studied at the Universities of Rome “Sapienza”, Leiden, and Oxford.

Jean Monnet Fellow between 2012 and 2014, I am currently a Research Associate at the European Union Democracy Observatory (EUDO). The long-term focus of my research is on the drivers of voters’ choice in Western Europe. I am particularly interested in the personalization of politics and its effects on voting behavior at the individual level. I have authored several academic papers and professional reports on the topic, including articles published in European Union Politics, Political Psychology, Party Politics, Political Research Quarterly, and West European Politics.

In 2014 I published a monograph on the topic: Personalization of Politics and Electoral Change (Palgrave Macmillan). Through analysis of election study data from Britain, Germany, and the Netherlands, the book shows that leaders matter, and matter increasingly, for the way individuals vote and, often, the way elections turn out.

In the last years, I have developed a growing interest in internet-based Voting Advice Applications (VAAs). In 2010 I co-edited with Lorella Cedroni Voting Advice Applications in Europe – the first volume ever devoted to the topic. Since 2013 I co-chair the section on VAAs at the ECPR General Conference. In 2014 I co-edited Matching Voters with Parties and Candidates together with Stefan Marschall (ECPR Press). Featuring the biggest number of European experts on the topic ever assembled, the book provides a comprehensive overview of the VAA phenomenon in a truly comparative perspective.

I am the founding convenor of the ECPR Research Network on Voting Advice Applications. I also sit in the Steering Committee of the Italian Political Science Association (SISP) and in the Scientific Council of the Italian National Election Study (ITANES).
