I am a Senior Fellow at the Center for Global Development and Director of the Market Shaping Accelerator. I study how people make political and social decisions — and what that means for governance and development. My current work looks at social norms of voting in semi-authoritarian contexts, government accountability in low- and middle-income countries, and inter-group relations. I also design and test approaches to reduce online misinformation and increase vaccination, and I write about applied research methods.
