I am a postdoctoral researcher at the University College London. I received my Ph.D from the Department of Electrical and Computer Engineering, Democritus University of Thrace in Greece. My research interests lie in the areas of network protocols, service differentiation and network management. Additionally, I am a founder of Araneous Internet Services (an IT company situated in North Greece). I have worked as a software engineer for many years, using different computer environments (Linux / Unix / Windows).
