Alessandra Renzi is Assistant Professor in Emergent Media for the Program in Media and Screen Studies and for the Department of Art + Design. Her work explores the linkages between media, art and activism through ethnographic studies and media art projects. Alessandra’s research interests have led her to study pirate television networks in Italy and the surveillance of social movements in Canada. Her book Infrastructure Critical: Sacrifice at Toronto’s G8/G20 Summit, co-authored with Greg Elmer, was published in 2012. As part of her past research on surveillance, she co-produced the documentary Preempting Dissent: Policing the Crisis. Her current research focuses on the impact of participatory networks and social media platforms on activist collaboration practices.
