Roberto Pugliese, born 1/04/1980 in Roma, Italy, is a doctoral researcher at the Department of Media Technology, Aalto University Finland, graduated in Electronic Engineering (M. Sc. from Roma Tre University, Italy) and completed a Master in Music and Media Technology (M. Phil. from Trinity College Dublin, Ireland). His research focuses on expanding human-computer interaction methodologies through the concept of enaction, that is the action-perception loop always in place in all sense-making activities sustained by bodily and spatial involvement. He works with physical interaction with sound, augmented performance by means of digital media and participatory installations. His work Traffic with Rachel O’Dwyer, has been exhibited at the Science Gallery (Dublin, Ireland, 2010) and Eyebeam (NY, 2011) and PuShy at the Plektrum Festival (Tallinn, Estonia, 2011). His current research agenda addresses collective music performance and its contextualization to the social dimension of enaction. For this, he develops new tools to analyze and author the process.
