Worked as an intern at the Americas Division of Human Rights Watch in New York and at the Center for Justice and International Law in Washington D.C.  Sergio is interested in exploring innovative approaches toward bridging gaps between law and local cultures and communities, in particular rural peasants (campesino) communities victims of violence and land dispossession in the region of Montes de Maria (northern rural Colombia), where he has done extensive fieldwork research in the past 14 years.  His research concerns the resolution of land tenure disputes and engages with debates on property, bureaucracy, transitional justice, international environmental law and peace.
