Giovanni Jona-Lasinio (born 1932), sometimes called Gianni Jona, is an Italian theoretical physicist, best known for his works on quantum field theory and statistical mechanics.

[2] At present, he holds a faculty position in the Physics Department of Sapienza University of Rome, and is a full member of the Accademia dei Lincei.

He spent several years abroad, doing his research also at University of Chicago (1959–60), CERN (1964–65), MIT (1965–66), Institut des Hautes Études Scientifiques (1980–81), Université Pierre et Marie Curie (1983–84).

In recognition of his colleague's work, Nambu asked Jona-Lasinio to hold the Nobel Lecture at Stockholm University in his place.

[5] As the Nobel Prize is awarded each year to at most three people for no more than two different research works, in 2008 the committee was forced to skip one member each from both the CKM and the NJL workgroups (incidentally, both of them Italian).
