He is well known for the "Ghirardi–Rimini–Weber theory (GRW), which he proposed in 1985 together with Alberto Rimini and Tullio Weber, and for his contributions to the foundations of "quantum mechanics. He independently rederived, in a referee report to Foundations of Physics, the "no-cloning theorem , before the works by "Wootters and "Zurek and by "Dieks in 1982, but after the actual first derivation by Park  in 1970.
His research interests related to a variety of topics of theoretical physics, but focused beginning in 1983 mainly on the foundations of quantum mechanics.
Ghirardi was a member of the editorial board of "Foundations of Physics and formerly of Studies in History and Philosophy of Modern Science. He was president of the Italian Society for the Foundations of Physics, of which he was one of the founding members.
The President of the Province of "Trieste, Maria Teresa Bassa Poropat, conferred the Sigillo della Provincia di Trieste to Giancarlo Ghirardi for research and teaching, for his commitment to the promotion and development of physics in Trieste and for his intense and fruitful activity as the author of popular books and scientific publications.
In 2017, he was awarded the Spirit of Salam prize for his extraordinary contributions to the development of the "International Centre for Theoretical Physics during its budding years, both at its scientific and organizational fronts.
