Early life and career.
Gelmini received her Ph.D. from the National University of La Plata in 1981. Her doctoral advisors were Roberto Peccei and Carlos A. Garcia Canal. 
Upon graduation, Gelmini worked at the Ludwig Maximilian University of Munich in Germany for a few years before moving to the International Centre for Theoretical Physics in Italy at around 1982. During this time, she was based at CERN in Switzerland. Gelmini was also affiliated with the Lyman Laboratory of Physics at Harvard University and the Enrico Fermi Institute at the University of Chicago between 1986 and 1988.
In November 1989, Gelmini joined UCLA as a faculty member and has been there ever since.
