Welcome to my academic website.

I am currently a postdoctoral researcher in the Archimides Research Unit at the Athena Research Center, working on the interplay between machine learning and mechanism design.

I have earned my PhD at the University of Liverpool, under the guidance of George Christodoulou, working in problems of mechanism design where monetary transactions are not possible.

My main research interests lie between computer science, economics and artificial intelligence, and mostly revolve around algorithmic game theory and mechanism design.

In the past I was affiliated with the Efficient Resource Allocation in 5G and Beyond Networks project at the University of Patras, working primarily on game-theoretic aspects of resource allocation in wireless networks. Previous to that I worked as a research assistant at the Citizen-Centric AI systems project of the University of Southampton.
