I am a PhD student enrolled in the Italian National Doctoral Programme in Artificial Intelligence, at the Department of Computer, Control, and Management Engineering (DIAG) Antonio Ruberti at Sapienza University of Rome, where I earned a master's degree (MSc) in Engineering in Computer Science.

The area my research is majorly focused on is Artificial Intelligence. More specifically, I am interested in the Knowledge Representation and Reasoning (KRR) semantic technologies, in the explainability and interpretability of Artificial Intelligence models (XAI) by means of the integration of Neural and Symbolic Artificial Intelligence techniques (Neuro-Symbolic AI).

My PhD supervisor is prof. Maurizio Lenzerini
