I am a third year PhD student in the theory group at Cornell University. I am very fortunate to be advised by Éva Tardos and be supported by the NDSEG fellowship. I am broadly working on Algorithmic Game Theory and Learning Theory problems. My most recent work has been on Mechanism Design and Online Learning with global constraints.

Before coming to Cornell, I received my BSE from the department of Electrical and Computer Engineering at the National Technical University of Athens. I completed my undergraduate thesis with Dimitris Fotakis, titled Perturbation Stability for Mechanism Design.

From July 2019 to August 2020, I was working at NCSR “Demokritos” in the Complex Event Recognition Group, advised by Alexander Artikis.

Work Experience

  • Research Associate at Complex Event Recognition Group, NCSR “Demokritos” Jul. 2019 - Aug. 2020
    I worked on an algorithm that compresses the route of a ship, to make a simpler trajectory with less points. This allows a complex event recognition engine (RTEC) to identify various events more quickly and accurate.
