Postdoctoral Prize Research Fellow in Politics

I am a Postdoctoral Prize Research Fellow in Politics at Nuffield College, University of Oxford. I hold a PhD in Political Science from the European University Institute.

My research is broadly situated in the fields of comparative politics and political behavior, and in my current work, I investigate questions such as:

In which issue areas is public opinion malleable, and in which is it resistant to change?
How can political elites influence the policy preferences and behaviors of voters?
What kinds of interventions can enhance political participation in democracies?

If you would like to learn more about my work, please visit my personal website, where you can find my CV and a list of my publications and working papers. You can contact me through my institutional email address or on Bluesky.
