Research

International Relations, Security, Conflict, Peacebuilding, Latin America

I study how international policies and global forces shape local peacebuilding, repression, and social resistance in Global South with a regional focus on Latin America. My current projects focus on former rebels’ transitions to nonviolent activism and community responses to punitive international drug control campaigns. Using primarily qualitative, mixed and fieldwork-based methods, my research aims to generate policy-relevant insights. My research has been published in several peer-reviewed journals.
