I am very grateful for this invitation to present my research in Mobilizing Ideas. As a young scholar, I have been studying social movements, trade unions and other forms of political participation using a variety of methods depending on the research question I needed to answer. Ethnography, life stories and process tracing are the ones I used the most. In this short text, I will focus on the following topics of my scholarly production: 1. Public deliberation and urban movements; 2. The youth condition and political participation; 3. The role of social movements, trade unions and protest on democratization; 4. The struggle of the poor for their socio-political reincorporation; and 5. The multiple scales in the resistance to the globalization of neoliberalism. My aim is to very briefly introduce the core questions and answers I have researched.
