My research has mainly focused on 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.
