About Me

I received my PhD from UCSD in 2013.

Previously, I was a PhD student in the Systems and Networking and Security groups. I worked under the supervision of Stefan Savage and Geoff Voelker. The title of my thesis was "Spam Value Chain: Defensive Intervention Analysis".

Cyprus - Akamas
I was born in Cyprus, a small island located in the eastern Mediterranean. In 2007 I received my B.Sc. in Computer Science from the University of Cyprus. I initially joined UCSD as a Master's student, after receiving a scholarship for graduate studies in the US from Fulbright.

I spent a big part of my undergraduate studies working part-time and during the summers on project DITIS. Specifically, I helped with the design and development for both desktop systems and mobile devices.

I am a member of the Hellenic Student Association at UCSD.
