I am a researcher with the systems and networking group at Microsoft Research, Cambridge, UK. My research interests span most aspects of computer communications and networks with my current focus being on data centers. In the past, I worked on Internet measurements and monitoring, home networks, social networks, and peer-to-peer networks. I have 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, I was an intern at Intel Research in Cambridge, UK working on Internet traffic classification, P2P networks and anomaly detection.
I received my Ph.D from the Computer Science department of the University of California, Riverside, and completed my undergraduate studies at the department of Applied Informatics of the University of Macedonia in Thessaloniki, Greece.
