His research focuses on state and collective responses to crime in urban-indigenous Latin America. His current project expands the analysis of linchamientos, acts of collective violence against alleged criminal offenders in the city of El Alto, Bolivia, to examine what precedes and what follows these acts of collective violence. In specific, he studies the factors behind the discretionary responses of state officials who at times prosecute the victims, and at other times, the perpetrators of these acts of violence.
