Halt and Catch Fire..

I am a PhD student in the Computer Science Department at UIUC, where I work with Prof. Josep Torrellas in the i-acoma group. I aspire to design fast and secure systems. My main research lies at the intersection of computer architecture, systems, and security, focusing on designing and building practical solutions that improve performance and bolster the security guarantees of large-scale datacenters.

During the summer of 2017 I ventured off to New York where I joined the Cognitive Systems and Data Centers group at the IBM TJ Watson Research Center. Throughout my internship I designed and exposed near-memory hardware primitives to the software stack to improve the performance of graph analytics.

The summer of 2015 I headed off to the temperamental city of Portland where I interned at the Accelerator Architecture Lab at Intel Labs. During my internship, I worked on an accelerator for Machine Learning augmented with high-bandwidth memory.

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 some brilliant people including Prof. Dionisios Pnevmatikatos who introduced me to the world of computer architecture. Prof. Apostolos Dollas who meticulously mentored our submission to the Altera Innovate Europe contest, and Prof. Ioannis Papaefstathiou who taught me the engineering attitude of "do or die". During the summer of 2012 I joined the CARV Laboratory at ICS, FORTH where I worked with Dr. Polyvios Pratikakis on reliable system design.
