Matteo Bortoletto

About

I am a PhD Student in the Collaborative AI group at the University of Stuttgart, Germany, advised by Prof. Andreas Bulling. My core research lies at the intersection of artificial and social intelligence.

Currently, I'm a Visiting Graduate Scholar at the SCAI Lab, Johns Hopkins University.

Research Interests

My research focuses on how AI can understand others' mental states such as desires, beliefs, and intentions — a concept known as theory of mind — and how this understanding can improve interactions between humans and AI. In particular, I work on:
