During 2013 to 2015, Diaz has developed projects that uses the concept of faunalización as a rhetorical device to cover issues related to urban violence. The use of this element not only responds to a problem of representation, but its connotations have to do with the image of animals, mimesis and eyes. Some authors talk about this type of mechanism as a crucial resource in analyzing violence, either from the individual or from the visual ethnographic- arguing that this form of representation humanizes what the human being dehumanized. Problematizing context, Diaz captures the nuances in both rural and urban areas where semantic and mimetic procedures present victims and perpetrators likened to beasts of prey hunting or objects.
He is currently conducting research on incorporating ethnographic strategies to address the use of language and urban behavior.
