I am an Associate Professor in Political Behaviour in the Department of Government at the London School of Economics and Political Science (LSE), and hold a D.Phil (2015) from Nuffield College, University of Oxford. I am affiliated with the LSE Data Science Institute, the LSE Electoral Psychology Observatory and the Public Opinion Analytics Lab.

As a behavioural and experimental political scientist I study media and campaign influence in the UK and in other advanced European democracies. I am particularly interested in how campaigns influence voters' behaviours and shape the composition of the electorate, in how journalists' coverage of extreme politicians shapes voters' beliefs, and in how political beliefs and behaviours diffuse in different types of social networks.

My methodological expertise is in field experimentation, the design, conduct, and analysis of randomized experiments in settings with high ecological validity. I often collaborate with political organizations to implement campaign interventions. I also use natural and quasi-experiments for causal inference and have a growing methodological interest in meta-analysis.

Some of my work has been published in the American Political Science Review, the American Journal of Political Science, the Journal of Politics, the British Journal of Political Science, Political Science Research and Methods, the European Journal of Political Research, the Quarterly Journal of Political Science. Electoral Studies, and the Journal of Experimental Political Science. My co-authors include Daniel Bischof, Diane Bolet, Eline de Rooij, Elias Dinas, Fabrizio Gilardi, Vicky Fouka, Peter John, Nikolay Marinov, Stuart Turnbull-Dugarte, Asli Unan and Alexander Wuttke.

At the LSE, I teach courses on political behaviour, research methods and experimental political science. I also regularly teach workshops on causal inference and field experiments in the UK and abroad. I am a member of EGAP, and co-organize the European Workshop in Empirical Political Science (EuroWEPS). I am also a member of the APSA President's task force on AI and democracy. Please feel free to get in touch if you are interested in doing a PhD at the LSE in areas related to my research interests.
