About Me

Hi there! I am a first year Master’s student at University of Waterloo’s Cheriton School of Computer Science where I am fortunate to be advised by professor Kimon Fountoulakis. My interests broadly span Theoretical Machine Learning, Statistical Learning Theory, and Optimization and their connections to deep learning. Before starting my master’s, I served as a Research Assistant at the Centre for Quantum Technologies in Singapore where I studied quantum attacks to post-quantum cryptosystems. Before that, I obtained my Bachelor’s degree in Pure Mathematics from the National and Kapodistrian University of Athens, ranking first in my cohort.

I am a proud recipient of a scholarship from the Onassis Foundation, for the support of my master’s studies!

Research Interests

Machine Learning: deep learning theory, out-of-distribution generalization
Statistic: statistical learning theory, domain adaptation
Optimization: convex optimization, optimization algorithms
