Halt and Catch Fire..

I will start as an Assistant Professor in the Computer Science Department and Electrical and Computer Engineering (by courtesy) at Carnegie Mellon University in Fall 2021. I will be spending the next year at Facebook Research. My research bridges computer architecture and operating systems focusing on performance, security, and scalability. My current work follows two central themes: (a) uncovering security vulnerabilities and building defenses at the boundary between hardware and OS, and (b) re-designing abstractions and interfaces between the two layers to improve performance and scalability.

I earned a PhD in Computer Science at the University of Illinois at Urbana-Champaign where I was fortunate to work with Prof. Josep Torrellas in the i-acoma group. My alma mater is the Technical University of Crete in Greece, where I studied Electronic and Computer Engineering. During my years in Crete I had the chance to work with Prof. Dionisios Pnevmatikatos, Prof. Apostolos Dollas, Prof. Ioannis Papaefstathiou and Prof. Polyvios Pratikakis.
