Yu, Y. Xie, M. Abadi, S. Savage, G.M. Voelker, A. Pitsillidis, April 2012, US 2012/0102169 A1. Misc 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.
