I am a second-year PhD student at University of Bern. My research interests include distributed systems and blockchains, consensus protocols, and multiparty computation.

Prior to joining UniBe, I graduated from the school of Electrical and Computer Engineering at National Technical University of Athens. I did my master thesis on network security with deep learning methods at Netmode Lab.
