About
Hello! I'm a Postdoctoral Fellow at the ARC at Georgia Tech .
Before joining GaTech I did my PhD at the CS Department of University of
Wisconsin-Madison where I was 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 ECE Department of National Technical University of Athens.
Here's a copy of my CV [Last Updated: September 2024]
