Welcome! I am currently a third year PhD student at the Computer Sciences Department of UW-Madison, where I am fortunate enough to be working with Prof. Dimitris Papailiopoulos. My current research interests revolve around Large Language Models, and both theoretical and practical aspects of Machine Learning and Deep Learning.

Before coming to Madison, I earned my BSc and integrated MEng from the ECE department of the Technical University of Crete. During this time, I had the opportunity to work with Prof. Aggelos Bletsas, focusing on asynchronous inference algorithms for ambiently powered wireless sensor networks [Diploma Thesis].
