British Academy Postdoctoral Fellow

I am a British Academy Postdoctoral Fellow in the Department of Politics and International Relations (DPIR) at the University of Oxford. I recently returned from a year as a Democracy Postdoctoral Research Associate at the Kellogg Institute for International Studies at the University of Notre Dame, where I had previously held a Visiting Fellowship.

My research lies at the intersection of regime change studies, subnational politics, political economy, and historical institutionalism. Broadly, I study how and why democratic trajectories diverge inside and between countries. Rather than treating democratic change as a nationally uniform outcome, my work examines how subnational institutions, local political equilibria, and historical legacies shape the emergence, resilience, and erosion of democracy.

Connecting comparative literatures on democratization, autocratization, subnational politics, and historical political economy, I seek to explain why some provinces consolidate democratic institutions while others stagnate or experience authoritarian reversal, and what these territorial divergences reveal about political development more generally. Although much of my empirical work focuses on Latin America—particularly Brazil, Mexico, and Argentina—the broader questions motivating my research extend well beyond the region.

Methodologically, I adopt a theory-driven mixed-methods approach, combining original datasets, archival research, comparative historical analysis, and advanced quantitative techniques. I believe rigorous causal and descriptive inferences are strongest when statistical evidence is complemented by deep contextual and historical knowledge.

Alongside my research, I have taught comparative politics, Latin American politics, and quantitative methods at Oxford, supervised graduate and undergraduate students, and held teaching appointments across several Oxford colleges. I am deeply committed to research-led teaching and to helping students develop the analytical and methodological skills needed to tackle substantive political questions.

Beyond academia, I occasionally work with governments, international organisations, civil society, and the media as a consultant on democracy, elections, institutional reform, and Latin American politics. If you are interested in collaborating or would like to discuss a consultancy project, you can find further information about my services here.

Outside work, I enjoy strength training, swimming, long walks, specialty coffee, science fiction, cinema, and occasionally unwinding with a game of StarCraft II.
