Research and Bio

I am a PhD Student at Uppsala University, research group UART (Uppsala Architecture Research Team) and also a Microsoft PhD Scholar, under the supervision of Professor Stefanos Kaxiras, and under the co-supervision of Associate Professor Magnus Själander (@ NTNU), Boris Köpf (@ Microsoft Research) and Assistant Professor Yuan Yao.
My research interests lie broadly on computer architecture and security, exploring novel ideas on hardware and software to design architectures that offer greater levels of security and performance. My research interests include exploring the design space of speculative execution threats and mitigations and secure memory.
My research is done in collaboration with Microsoft Research at Cambridge.
Prior joining Uppsala University, I graduated from a Master of Engineering program in Electrical and Computer Engineering at University of Thessaly, Greece, where I was a member of Computer Systems Laboratory (CSL) and Circuits and Systems Laboratory (CASLab).
