Itai Himelboim from the Grady College of Journalism and Mass Communication at the University of Georgia where he studies the role social media plays in news, political and international communication. He applies network analysis to examine political talk and information flow to identify the naturally occurring patterns of communications among social actors in online spaces.  His research explores how these patterns reveal how people choose information sources.  Network analysis of social media reveals the most strategically connected users – hubs and bridges – in these online discussions, highlighting the new roles news media play in interpersonal-communication spaces.  He has published in Journalism and Mass Communication Quarterly, Journal of Broadcasting and Electronic Media, Communication Research, and Journal of Computer-Mediated Communication.
