About Me

I am a PhD candidate in the Department of Computer Science at Cornell University. My research interests lie in Distributed Systems and more specifically in their scalability and self-organization aspects. I am also interested in Algorithms, especially those designed for distributed computation. My advisor is Robbert van Renesse and we are currently working on the moving target defense problem and how we can improve a system's fault-tolerance by introducing dynamicity at the protocol level. In the past, we have worked on cache placement strategies for cooperative caches in the context of online social networks. My committee also includes  Prof. Johannes Gehrke, Prof. Dexter Kozen and Prof. √Čva Tardos. My graduate minor is in Applied Mathematics.
I interned with the Computer Systems and Networking group at R.A. Microsoft Research, Cambridge during June-August 2013. I have also worked as a research member at R.A. Computer Technology Institute, Research Unit 1 from 2010-2011. I received my Dimploma in Computer Science and Engineering from the Department of Computer Engineering and Informatics at the University of Patras, Greece in 2010.
