Alessandro Bellina is a PhD student in physics at Sapienza University of Rome, where he has been enrolled since 2022, and is also affiliated with the Centro Ricerche Enrico Fermi and the Sony Computer Science Laboratories in Rome. Bellina's research spans statistical physics, complex systems, and the quantitative study of language, with work on topics including novelty dynamics in urn models, centrality measures in networks, and economic complexity. More recently, Bellina has investigated social influence in artificial intelligence, examining how multimodal language models exhibit conformity-like behavior consistent with Social Impact Theory. This line of work connects computational modeling with questions about opinion dynamics and the behavioral properties of AI agents.
