Background

I joined Nokia Research Center (NRC) in July 2001 and was a Principal Member of Research Staff at the Pervasive Computing Group of NRC Cambridge (MA, USA) and a Research Affiliate at MIT Computer Science and Artificial Intelligence Laboratory (CSAIL) until December 2008. I am currently a Senior Architect in the R&D organization of Nokia Services, in Burlington, MA.

I received my Dipl. Ing. from the National Technical University of Athens (NTUA) in 1994, and my M.Sc. and Ph.D. both in Electrical Engineering from Northeastern University, Boston, MA, in 1996 and 2001 respectively. From 1993 to 1994 I was an R&D Engineer at the Microwave and Optical Systems department of Intracom S.A., Athens, Greece. From 1996 to 2001 I was a Member and later a Senior Member of the Technical Staff with the Network Planning, Wireless Systems and Mobile Networking Systems departments of GTE Laboratories, Verizon Technology Organization and BBN Technologies respectively, all Corporate Research & Technology units of Verizon Inc. In these positions I conducted research on performance modeling of 2G and 3G CDMA cellular networks.

 

Research Interests

My main research area is Pervasive Computing and Internet Services. My research interests include distributed computing, hybrid P2P/Internet architectures, and security, with particular emphasis on system design that makes the user interaction with such systems intuitive and easy-to-use. Other areas where I have conducted research in the past are CDMA cellular systems, proximity (WPAN, WLAN) and ad-hoc networking, and the physical layer of CDMA-based systems.

Research Projects

Latest (2006-2008):
MyNet/UIA: Secure, peer to peer, personal overlay networks

The MyNet project creates technology that allows non-expert users to easily create secure personal networks of their devices and use them to interact with the personal networks of other users in their social environment. Click here for an overview video of MyNet on YouTube.

I was the technical lead of the MyNet personal and social networking services platform. My work included architecture, system design, and prototyping. Examples of my work include intuitive security, secure resource discovery, and architecture for hybrid P2P/Infrastructure Internet services.

 

Supporting/Other Information

Professional Activities

In 2005 I was elected a Senior Member of the IEEE, where I am currently a member of the Computer and Communications societies. I have served in the Technical Program Committees and as a reviewer of numerous IEEE conferences and publications.

I have served in the Editorial Board of the Digital Living Network Alliance (DLNA) for DLNA v1.5. I was also an active contributor of the DLNA Mobile Handhelds Subcommittee (MHS) from February 2004 until September 2005.
