About Me

My main research and teaching areas are comparative politics and quantitative methodology. In comparative politics, my research interests focus on the politics of authoritarian regimes, in particular transitions to democracy, anti-regime collective action, mass media, public opinion, and censorship. In quantitative methodology, I'm interested in research design and causal inference in experiments and observational studies.

My current research, conducted jointly with various co-authors, addresses topics such as censorship, regime propaganda, and protest in Russia, cults of personality, sponsorship effects in online surveys, and religious discrimination by PK-12 principals. My empirical research has an explicit focus on causality and uses either field experiments or carefully designed observational studies to draw robust causal inferences.

My past research includes work on the effects of West German television and radio on regime legitimacy and the diffusion of collective action in East Germany, voting behavior in Germany and Great Britain, the specification of regression-discontinuity designs, efficient estimators for field experiments with non-compliance, treatment effect heterogeneity and generalizability in randomized experiments, the combination of the double sampling design and non-parametric worst-case bounds to address missing outcome data in randomized trials, and the use of electromagnetic signal propagation models in social science research.

With Charles Crabtree, I'm organizing a yearly conference-within-a-conference during the annual SPSA meeting on the Politics of Authoritarian Regimes. Past programs: 2018, 2017, 2016.

I'm also organizing the Virtual Workshop on Authoritarian Regimes (VWAR) with Charles Crabtree.
