About Me

I am a research scientist at Huawei Noah’s Ark lab in London. Previously, I was a PhD student at the University of Edinburgh supervised by Dr. Stefano Albrecht. My PhD research was mainly focused on multi-agent reinforcement learning. Before moving to Edinburgh, I completed a Diploma (combined BSc and MSc) in Electrical and Computer Engineering at the Aristotle University of Thessaloniki. I have completed two research internships; one in team SequeL in Inria-Lille and one in Dematic.
