About

Hello! I'm a final year PhD student at the Computer Sciences Department of University of Wisconsin-Madison where I'm very fortunate to be advised by Christos Tzamos. I'm broadly interested in designing algorithms under uncertainty, approximation and online algorithms, mechanism design and machine learning.

Before joining UW-Madison I did my undergrad in Greece, in the Electrical and Computer Engineering Department of National Technical University of Athens.

Here's a copy of my CV [Last Updated: December 2023]
