His research interests related to a variety of topics of theoretical physics, but focused beginning in 1983 mainly on the foundations of quantum mechanics.
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.[9]
