About Me
I'm a second-year PhD student in the Electrical and Computer Engineering department at the University of Wisconsin–Madison, advised by Prof. Dimitris Papailiopoulos. My research interests lie in Large Language Models, Artificial Intelligence, and Machine Learning.
Before moving to Madison, I completed my BSc and integrated MEng at the Technical University of Crete, in the ECE department. There, I worked with Prof. Aggelos Bletsas on asynchronous inference algorithms with a focus on security applications.
