I am an Italian theoretical physicist with a background in statistical mechanics.

During my PhD, I focused my research on Machine Learning applications in Physics. In particular, the recurrent theme of my work has been what we called "Artificial Scientific Discovery".

This long-term ambitious goal concerns the question of how a machine can infer knowledge and set up models from observations of the world, produce hypotheses and decide on which experiments to perform to validate or reject its predictions, in a similar way to what human scientists do.

The tools needed to take the first step in this field are adapted from machine learning and involve representation learning and feature extraction, active learning and bayesian experimental design, information theory.

For more information about Machine Learning in Physics, please look at the online courses offered by the head of our group, Prof. Florian Marquardt, both the introductory course and the advanced course.

You can find more information on the theme of Artificial Scientific Discovery by watching the videos of the talks of the Artificial Scientific Discovery workshop Prof. Florian Marquardt and I organized during Summer 2021.

For information about the work on "Renormalized Mutual Information", you can look here for an accessible introduction and in the tutorial notebook for a more technical description.
