About Me

I am a Research and Development Engineer working on the TwinODIS project at the Institute of Computer Science at FORTH. I received my MSc in Computer Science from the University of Crete, where I had the privilege of being advised by Prof. Michail Fasoulakis. During my master's, my thesis focused on developing and analyzing new algorithms for two-player zero-sum games. Prior to this, I completed my MEng in Electrical and Computer Engineering at the National Technical University of Athens where I am proud to be advised by Dimitris Fotakis.

My research is driven by a broad interest in Algorithmic Game Theory, Optimization Theory, and Machine Learning. So far, I have spent most of my time analyzing how agents learn and converge in highly structured environments, like two-player zero-sum games. This has led me to explore topics like the last-iterate convergence properties of FLBR-MWU dynamics and descent-based approaches to the duality gap. However, my curiosity increasingly draws me to less structured, large-scale environments, and I am eager to explore how these game-theoretic dynamics translate to Reinforcement Learning.

Prospective PhD Advisors: I am actively seeking a PhD position focused on learning in games and multi-agent systems. I welcome the opportunity to connect with PIs whose research aligns with my background.
