Vasilis Papageorgiou
Hello! I am a 3rd year PhD student in Computer Sciences at the University of Wisconsin-Madison, advised by Dimitris Papailiopoulos. My research interests revolve around Large Language Models (LLMs), Machine Learning, and Deep Learning, with a focus on both theoretical and practical aspects.
Previously, I earned my diploma in Electrical and Computer Engineering from the Technical University of Crete, Greece, where I worked with Prof. Aggelos Bletsas on asynchronous algorithms for distributed inference in wireless sensor networks.
Currently, I am also a research intern at AWS AI Labs in Pasadena, CA, where I work on reasoning models.
