Stefano Civelli

HDR Student in AI at UQ

I am a Master of Philosophy (MPhil) student in Computer Science at The University of Queensland, focusing on Large Language Models (LLMs).

Previously, I worked for a small startup in Milan, obtained my Master's degree in Computer Science from Politecnico di Milano (POLIMI) and then worked as a Research Assistant at The University of Queensland.

I am also Tutor for DATA7201 at UQ.
