Alessandra Renzi is an activist and researcher, exploring the linkages between media, art, and activism through ethnographic studies and media art projects.

As part of her research on surveillance, she co-produced the collaborative documentary Preempting Dissent: Policing the Crisis. At the moment, Alessandra is investigating the use of participatory mapping platforms and big data for social justice in Indonesia and the US.
