Roberto Percacci is an Italian theoretical physicist known for work in quantum gravity and the asymptotic safety program. He has held positions at the International School for Advanced Studies, CERN, and the University of Florence, and has published influential results on renormalization group methods and effective field theory approaches to gravitation. Percacci's work intersects with research by Steven Weinberg, Richard Feynman, Abdus Salam, Frank Wilczek, and groups at Princeton University, Imperial College London, Max Planck Institute for Gravitational Physics, and University of Cambridge.
Percacci was born in Florence and studied physics at the University of Florence and completed doctoral work amid collaborations with researchers at Scuola Normale Superiore di Pisa, SISSA, and laboratories associated with INFN and CERN. During his formative years he was influenced by the work of Albert Einstein, Erwin Schrödinger, Paul Dirac, Enrico Fermi, and contemporaries at Sapienza University of Rome and University of Padua. His early training combined exposure to research groups in Italy, exchanges with scholars at Harvard University, Princeton University, and visits to institutes such as the Max Planck Society and CNRS.
Percacci's academic appointments have included positions at SISSA, the University of Florence, and visiting posts at CERN, Perimeter Institute for Theoretical Physics, University of California, Berkeley, and New York University. He has taught courses related to topics developed at ETH Zurich, University of Oxford, Yale University, and Columbia University and supervised students who later joined faculties at Brown University, University of Chicago, and University of Toronto. Percacci participated in collaborative networks with researchers at European Organization for Nuclear Research, Institut des Hautes Études Scientifiques, and consortia involving INFN, Fermilab, and Lawrence Berkeley National Laboratory.
Percacci contributed significantly to the asymptotic safety scenario for quantum gravity originally proposed by Steven Weinberg, employing functional renormalization group techniques developed in part by researchers at Max Planck Institute for Gravitational Physics, Institut des Hautes Études Scientifiques, and groups around Christof Wetterich. His work addressed nonperturbative renormalization flows, fixed points, and truncation schemes in gravity, building on methods used in studies at CERN and Perimeter Institute for Theoretical Physics. Percacci explored effective field theory descriptions of gravitation in contexts related to analyses by Donoghue, John F. Donoghue, Gerard 't Hooft, and Martinus Veltman, and connected these to symmetry-breaking mechanisms analogous to approaches in Higgs boson physics studied at CERN and Fermilab. He investigated scalar-tensor theories, bi-metric formulations, and applications of renormalization group equations relevant to researchers at Imperial College London, University of Cambridge, and Stanford University. His collaborations and citations link his work to that of Claudio Burgess, Michael Duff, Roberto Jackiw, Gianfranco Bertone, Tom Banks, Juan Maldacena, Cumrun Vafa, Edward Witten, and groups studying quantum cosmology at Kavli Institute for Theoretical Physics.
Percacci has been recognized by institutions including SISSA, University of Florence, the Italian Physical Society, and was invited to lecture at meetings of International Centre for Theoretical Physics, European Physical Society, and conferences organized by Royal Society and American Physical Society. He has delivered plenary talks at workshops associated with Strings Conference, Loops 'XX, and symposia at Perimeter Institute for Theoretical Physics and Institut Henri Poincaré.
Percacci authored and coauthored papers and books cited across literature associated with Physical Review Letters, Physical Review D, Journal of High Energy Physics, Classical and Quantum Gravity, and proceedings of Les Houches and Strings Conference volumes. Notable works include studies on renormalization group flows, asymptotic safety reviews, and monographs used by researchers at SISSA, Perimeter Institute for Theoretical Physics, CERN, University of Cambridge, and Princeton University.
Percacci's career fostered connections among researchers at SISSA, University of Florence, CERN, INFN, Perimeter Institute for Theoretical Physics, and universities including Harvard University and Princeton University. His mentoring influenced scholars working at Max Planck Institute for Gravitational Physics, Imperial College London, Stanford University, and University of Chicago. Percacci's contributions remain part of ongoing research programs in quantum gravity pursued at European Organization for Nuclear Research, Kavli Institute for Theoretical Physics, Perimeter Institute for Theoretical Physics, and departments worldwide.
