Research Interests:

My research interests include political behaviour, comparative politics, social media and politics, and political methodology. My doctoral research aimed to provide a general theory of online social capital and its effects on political participation. My research now focuses on electoral politics, elite politics (candidates and legislators), techniques for latent variable estimation, and the study of false information.
