Halt and Catch Fire..

I am an Assistant Professor in the Computer Science Department and Electrical and Computer Engineering (by courtesy) at Carnegie Mellon University since Fall 2021. Before, I spent a 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 in 2020 where I was fortunate to work with Prof. Josep Torrellas in the i-acoma group. My PhD thesis, Rethinking Computer Architecture and Operating Systems Abstractions for Good & Evil, received the 2021 ACM SIGARCH & IEEE CS TCCA Outstanding Dissertation Award, for "contributions to redesigning the abstractions and interfaces that connect hardware and operating systems". 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.
