I am an Assistant Professor and Andrew and Erna Viterbi Early Career Chair in the Department of Computer Science at the University of Southern California. I am member of the CS Theory group and the Machine Learning center.

Prior to joining USC's faculty, I spent two years at UC Berkeley as the Simons Postdoctoral Fellow in Theoretical Computer Science, and then I was a faculty member at the University of Edinburgh. I obtained my Ph.D. in Computer Science at Columbia University, advised by Mihalis Yannakakis. Before that, I did my undergraduate studies in Greece, at the National Technical University of Athens.

Research Summary

My main research interests are in algorithms, learning, statistics, and applied probability. A major goal of my work is to understand the tradeoff between statistical efficiency, computational efficiency, and robustness for fundamental problems in machine learning. I also have strong interests in optimization, game theory, and their connections to learning.
