Hello and welcoStefanosme to my personal website!

I am a Postdoctoral Research Fellow at the ESD Pillar of Singapore University of Technology & Design (SUTD), where I am advised by Georgios Piliouras. Before coming to Singapore, I earned my PhD in Game Theory (Operations Research) from the Mathematics Department of Athens University where I was advised by Costis Melolidakis.

My research interests are in Game Theory, Operations Research, and Multiagent Systems, including Blockchains and Artificial Intelligence.
