About Me

I am a research fellow at Input|Output. Previously, I was a post-doctoral researcher at the Department of Informatics and Telecommunications of the University of Athens. I obtained my PhD from the University of Edinburgh under the supervision of Aggelos Kiayias, and hold a Diploma in Electrical and Computer Engineering from the National Technical University of Athens.

I do research in the intersection of Distributed Computing, Cryptography, and Game Theory, with a special focus on blockchain-related topics.
