About Me:

I am a PhD student, enrolled jointly at the Department of Informatics and Telecommunications of the National and Kapodistrian University of Athens (NKUA) and Archimedes Research Unit, where I am fortunate to be advised by Prof. Christos Tzamos (NKUA) and Prof. Constantine Caramanis (UT Austin).

Prior to pursuing my PhD, I completed a BSc in Mathematics with a specialization in statistics at the University of Patras, where I graduated as the valedictorian of my class. I then graduated with distinction both from the MSc in Statistics at Imperial College London, followed by the MRes in Statistics and Operational Research at Lancaster University.

Now, I'm dedicated to my PhD, with a focus on theoretical machine learning, statistical learning, optimization, and algorithms, aimed at contributing to cutting-edge research in these fields.
