Thomas Karagiannis is a researcher with the systems and networking group at Microsoft Research, Cambridge, UK. His research interests include Internet measurements and monitoring, analysis and modelling of Internet application traffic dynamics, social networking, peer-to-peer networks, software update dissemination and anomaly detection. He received his Ph.D at the Computer Science department of the University of California, Riverside under the supervision of Associate Professor Michalis Faloutsos. Dissertation title: '' Novel Techniques and Models for Network Traffic Profiling: Characterizing the Unknown ''.
Thomas spent the summer of 2003 at CAIDA developing methodologies to identify and measure peer-to-peer file-sharing traffic at the Internet core. From July 2004 to May 2005 and from October 2005 to April 2006, he was an intern at Intel Research in Cambridge, UK working with Dina Papagiannaki on Internet traffic classification, P2P networks and anomaly detection. He received his B.S. at the department of Applied Informatics of the University of Macedonia in Thessaloniki, Greece.
