Trejo is currently pursuing three research agendas: 1) A study on indigenous resistance to criminal governance and narco rule in Mexico; 2) a study of ecosystems of local violence, focusing on selective violence and the assassination of local political, social, and economic leaders in Mexico’s criminal wars; and 3) an in-depth study of internationalized prosecution as a strategy to dismantle criminal structures by means of law and not war based on the Guatemalan collaboration with the United Nations.

For his policy and practice activities, Trejo serves as external adviser to various human rights and peacebuilding NGOs in Mexico and to collectives of families of victims of forced disappearance.
