I have been a graduate student at M.I.T, a postdoc in Saclay, and a CERN fellow. I have been a staff physicist with INFN from 1990 to 2002, in Torino and Rome. Since January 2003 I am full professor of theoretical physics at the University of Milan, where, among others, I served as a member of the academic board from 2010-2015. I have been a visiting professor in Barcelona, a visiting fellow in Edinburgh and at Ecole Polytechnique, and a visiting lecturer at Ecole Normale Supérieure de Lyon, and a scientific associate of the Discovery Center at the Niels Bohr Institute.
I am currently a scientific associate of the Higgs Centre in Edinburgh, and I am a member of the editorial board the European Journal of Physics C. Since October 2023 I am Editor in Chief of Journal of Physics G and
I have played some role in past particle physics facilities as a member of the SPS committee at CERN from 2001-2004 and as a convenor of the HERA-LHC workshop from 2004 to 2008; on present experiments as a member of the steering group of the PDF4LHC  workshop and in various capacities in the Higgs cross section working group; and on possible future facilities as a member of the steering committee and the international advisory committee of the LHeC.
Among my past and present collaborators, a special role has been played by  Guido Altarelli in Rome and CERN, Richard Ball in Edinburgh, José Ignacio Latorre in Barcelona, and Giovanni Ridolfi in Genova.

Research Interests

My research is mostly focussed on the theory of  strong interactions, perturbative QCD, currently of great interest because of the needs of physics at the LHC, in particular in the study of the properties of the Higgs boson. An extended effort has gone into resummation: the development of computational techniques for the perturbative computation of particular classes of perturbative contributions to all orders in the strong coupling. As a spokesperson of the NNPDF collaboration, I was amongst the first to propose the use of AI methods in theoretical particle physics in the context of the determination of the parton distributions (PDFs) which encode the structure of the nucleon. More recently I have been pursuing in the same context the development and use of modern machine learning metohdologies.
In 2017 I have been awarded an ERC advanced grant, which has supported the N3PDF project, that over the years from 2018 to 2023 has developed new artificial intelligence methods and improved theoretical and methodological results in precision standard model physics for the determination of PDFs.
I have also worked on various aspects of quantum field theory, specifically anomalies, i.e. the quantum breaking of a classical symmetry, fractional statistics, i.e. 2+1 dimensional particles which are neither bosons nor fermions, and the structure of renormalization group flows.
