Giorgio Parisi

Emeritus Professor at Sapienza University of Rome and Nobel Prize in Physics

Giorgio Parisi (Rome, 1948) is an Italian theoretical physicist and winner of the 2021 Nobel Prize in Physics, internationally recognised for his work on complex systems, statistical mechanics and quantum field theory. Professor Emeritus at La Sapienza University of Rome and former president of the Accademia Nazionale dei Lincei, he has dedicated his career to understanding phenomena characterised by disorder, fluctuations and collective behaviour.

His research has had a profound impact not only on theoretical physics, but also on interdisciplinary fields such as artificial intelligence, neuroscience, biology, economics and the study of social systems. Among his most celebrated contributions are his studies on spin glasses, chaotic dynamics, turbulence and mathematical models of the collective behaviour of animals, such as flocks of starlings.

The author of hundreds of scientific publications, Parisi has received numerous international awards, including the Wolf Prize and the Boltzmann Medal, prior to the Nobel Prize awarded ‘for the discovery of the interplay between disorder and fluctuations in physical systems from the atomic to the planetary scale’.

Alongside his scientific work, he has always been committed to popularising science and defending public research, contributing to the cultural and civic debate in Italy.
