Lorenzo Lupo

I am a senior scientist experienced in research, software development, project management, teaching, and consultancy. My background spans multiple disciplines, including machine learning, computational social sciences, and management, with a special interest in the societal impacts of AI.

My recent work includes evaluating the impact of AI on Wikipedia, investigating LLMs' simulation capabilities of entire demographic groups, and bulding agents specialized in Italian notary law.

After completing my PhD on neural machine translation at Grenoble Alpes University, I held research positions at the University of Milan and Bocconi University, where I currently work as a freelance researcher, collaborating with Kai Zhu, Nicolò Cavalli, the MilanNLP research group, and others.
