I am an internet and technology researcher completing my PhD in Media, Technology and Society at Northwestern University. I’m interested in social computing, computational linguistics, social network analysis, human-computer interaction and knowledge management.

My dissertation examines leadership in online communities, combining automated text analysis, social network analysis and statistical evaluation to identify communication behaviors and networks in large-scale discussion groups.

My previous scientific papers have examined how adolescents behave and present themselves on the internet, how users collaborate, negotiate or share expertise in online settings, and how internet technology can be used for e-learning or knowledge management. I have also designed and developed web sites since 1996.

My research has been highlighted on CBS, NBC, BBC, USA Today, New Scientist and Science News among others.
