Biography
I am a Postdoctoral Researcher in Cryptography at UC Berkeley hosted by Sanjam Garg.
In February 2024, I received my PhD from IMDEA Software Institute and Universidad Politécnica de Madrid where I was advised by Dario Fiore. I received my Diploma in Electrical and Computer Engineering from the National Technical University of Athens.
At the core of my research is Cryptography, its theoretical foundations and its applications. My current focus is on building provably secure cryptographic protocols, with an emphasis on Succinct Cryptographic Primitives, Proof Systems and Advanced Encryption Schemes. My work has been motivated by the Blockchain Technology, the growing privacy concerns in the digital world and the combination of the two.
My PhD thesis is here.
