I am Nassos, an ECE PhD Candidate at the COEUS Center at the Georgia Institute of Technology. I am advised by Dr. Angelos Keromytis. My research interests lie at the intersection of IC design and hardware security, focusing on hardware trojan attacks on modern microarchitectures and their implications for global chip supply-chain security. Other topics of interest include computer architecture and side-channel analysis. I am always looking for collaborations in the above areas, so feel free to drop me an e-mail.
