NLP, LLMs, Safety

I am a PhD student at the University of Modena and Reggio Emilia under the supervision of Prof. Sonia Bergamaschi, and a visiting researcher at the DARE Lab, working with Dr. Georgia Koutrika. My research focuses on Large Language Models (LLMs), both in real-world applications and safety, and is part of the ITSERR project funded by the EU. Over the past year, I have worked on several papers, including [ACL25] and [TPDL24].

I hold both a BSc and MSc in Computer Engineering, with a specialization in Machine Learning and Computer Vision. I also received a research grant at A.I. Tech S.R.L., where I worked on Artificial Intelligence.
