Office: C37

I am a Senior Researcher at CNR-ISTI and External Prof. at UNIPI.

I am also a member of the KDD-lab: a joint research team that connects the Computer Science Dept. of the University of Pisa, CNR-ISTI, and SNS.

Within the lab, I coordinate the research activities on Complex Network Analysis.

My research focuses on modeling, characterizing and forecast emerging (social) behaviors leveraging complex networks and AI/ML techniques.

My recent research spans over the following topics:

I am always open to new collaborations and opportunities.

YSocial: A Social Media Virtual Twin

Social Media Digital Twin Agent-Based Simulation

An open-source framework designed to model, simulate, and analyze opinion dynamics and user behavior in polluted information environments. Leveraging Large Language Models (LLMs) and complex network analysis, YSocial acts as a digital twin for social platforms.
