Silvia Bisi joined the Nexa Center for Internet & Society as a fellow in January 2010. She’s a lawyer, with a Post-graduate Master of first level in “IT Law and Legal Informatics” and a Ph.D. on the same subject from the University of Bologna. Her research interests are mainly focused on data protection issues and, more generally, ICT and fundamental freedoms issues. At the Nexa Center, she researched about anonymity of Internet users in order to analyse the consequences on privacy, fundamental freedoms, innovation and business models of a duty to identify users and track their on-line activities. As part of her Nexa fellowship, Silvia will produce an English version of her aforementioned research, continuing at the same time to collaborate with the Center on some specific data protection issues.
