I’m a third-year CS PhD student at Boston University, working with Professor Aldo Pacchiano. My research interests include bandit algorithms, reinforcement learning, and online learning with a focus on safety constraints and optimal decision-making under uncertainty.

Prior to my studies at Boston University, I received my Integrated Master’s degree in Electrical and Computer Engineering from the National Technical University of Athens, Greece, where I worked with Professor Dimitris Fotakis and Evripidis Bampis on scheduling algorithms with predictions.
