I am a Principal Inventive Scientist at AT&T Labs, USA. My research interests are mainly in the area of network architecture and security, network system design and troubleshooting, middleware architectures and solutions, measurement-based techniques, and implementation of cross-layer mechanisms that span the entire network protocol stack. I received my PhD from the Department of Computer Science & Engineering at the University of California, Riverside in 2007, under the supervision of Srikanth Krishnamurthy and Michalis Faloutsos. 

From January 2010 to August 2012 I was an R&D Engineer at Alcatel-Lucent, USA, where I worked on security standards for network and middleware systems, as well as on end-to-end security solutions for multimedia over IP and secure cloud services. From February to December 2009, and from July to September 2008 I was a visiting researcher at UC Riverside in the Networks and Communications Laboratories, where I worked on smartphone and network security, as well as wireless network coding. From January 2008 to February 2009 I was a researcher at CERTH, working with Leandros Tassiulas on developing network coding frameworks and testbed federations. From August 2008 to January 2009 I was an adjunct assistant professor in the Department of Computer & Communications Engineering at the University of Thessaly, Greece. From July 2006 to December 2006 I was an intern at Intel Research in Cambridge, UK, working on the SWAN project (Self Organized Wireless Access Networks). During summer 2005 I was an intern at Nokia R&D in Boston, MA, working with S. Keller on performance evaluation techniques for mobile Internet browsers. During summer 2001 I was an intern at Cosmote S.A in Athens, Greece, working on coverage optimization procedures and tools for cellular networks. 

I received my MSc degree in Computer Science & Engineering at the University of California, Riverside (June 2005), and my Diploma in Electronics & Computer Engineering, at the Technical University of Crete, in Greece, in June 2003. During the latter, I worked with Michael Paterakis on evaluating the ability of 802.11-based WLANs to support video-conference applications.
