I am a PhD student in the Systems Research Group at the Computer Laboratory of the University of Cambridge, under the supervision of Steve Hand. My general interests include systems and security. In particular, I am working on techniques to improve the security and reliability of systems code. My key approach has been to devise new integrity properties that are effective against attacks but at the same time cheap to enforce at runtime.

In the past I have studied wireless malware and worked on malware detection at the network level. I received an M.Sc (2005) and a B.Sc. (2002) from the Computer Science Department, University of Crete, Greece, under the supervision of Prof. Evangelos Markatos.

I expect to graduate in late 2010. [Short CV]
