I am a PhD candidate at the Department of Computer Science and Engineering at Washington University in St. Louis, supervised by the amazing William Yeoh.

My current research interest is centered on developing human-aware decision-making frameworks for enabling and enhancing human-AI collaboration. My work is inherently interdisciplinary and requires drawing ideas from a confluence of approaches such as knowledge representation & reasoning, planning, machine learning, as well as philosophy, cognitive science, and psychology.

Within a preceding historical epoch, I received a MSc. in Artificial Intelligence from the University of Southampton (UK), supervised by Long Tran-Thanh, a MSc. in Applied Mathematics from the University of Glasgow (UK), supervised by Radostin Simitev, and finally a BSc. in Statistics and Actuarial-Financial Mathematics from the University of the Aegean (GR), supervised by Nikolaos Kavallaris.
