My research interest lies in understanding the relationship between economic development and the distribution of economic activity in space. I have analyzed this relationship through a range of theoretical approaches, including new economic geography, agent-based and urban economics models, and also through empirical analyses of regions and cities in India, China, Colombia, Sub-Saharan Africa and Brazil. Inevitably, my research interests have converged to one topic: understanding urban agglomerations in developing countries, the main focus of my current research.
