Speakers

Albert-László Barabási

Albert-László Barabási is a network scientist, fascinated with a wide range of topics, from unveiling the structure of the brain to treating diseases using network medicine, from the emergence of success in art to how does science really works. His work has helped unveil the hidden order behind various complex systems using the quantitative tools of network science, a research field that he pioneered, and lead to the discovery of scale-free networks, helping explain the emergence of many natural, technological and social networks.

Giulio Biroli is professor of theoretical physics at ENS Paris. He is PI of the Simons collaboration « Cracking the glass problem » and holds a PRAIRIE chair on interdisciplinary applications of Machine Learning. He is the director of the Beg Rohu summer school of statistical physics and condensed matter. For his work on glass and jamming transition he received in 2007 the Young Scientist Award (the junior Boltzmann medal) of the International Union of Pure and Applied Physics and in 2018 the Prix d’Aumale. 
Biroli has published over 120 peer-reviewed articles. His research focuses on statistical physics, theoretical condensed matter, theoretical physics and inter-disciplinary applications of physics to machine learning and biology.
