About me

I am a PhD student at the Computer and Information Sciences Department of University of Pennsylvania, working with Renè Vidal. I am also affiliated with the GRASP lab at UPenn.

My research interests lie at the intersection of (multi-agent) optimization, deep learning theory and theoretical computer science.

Before coming to the States, I graduated with a Diploma in Electrical and Computer Engineering from Greece, where I worked with Dimitris Fotakis and Pavlos Efraimidis on the intersection of opinion dynamics and theoretical computer science.
