Odysseas S. Chlapanis
I am a PhD student at Athens University of Economics and Business and Affiliate Researcher at Archimedes Research Unit. My research is focused on evaluating and improving the reasoning capabilities of LLMs on legal tasks (LegalNLP). I am also very interested in developing practical LLM applications.
