Baldassare Di Bartolo is a Professor of Physics at Boston College, Chestnut Hill, Massachusetts, which he joined in September 1968. He received his first degree, Dottore Ingegnere, in Industrial Engineering, at the University of Palermo, Italy, from where he has graduated in 1950. After a year of post-graduate studies at the Istituto Superiore delle Telecomunicazioni in Rome, he was granted a Diploma of Specialization in Telecommunications. Another Diploma of Specialization in Radar Technique followed in 1953, was granted by the Consiglio Nazionale delle Ricerche in Rome, after an additional year of post-graduate studies. From 1953 to 1956 he worked with the Microlambda Company in Naples as a design engineer in the field of microwave components and taught courses on Information Theory at the Istituto Universitario Navale in Naples.

In 1956 he received a Fulbright grant and a scholarship from the Massachusetts Institute of Technology (MIT) where he worked as a member of the "Foreign Student Summer Project"; he returned to MIT in 1957 as a visiting fellow at the Department of Physics. In 1958 he became a staff member of the Laboratory for Insulation Research of MIT and from 1960 to 1963, while still with this laboratory, he was a graduate student in Physics. He received a Ph.D. in Physics from MIT in 1964. From 1964 to 1968, Dr. Di Bartolo directed the Spectroscopy Laboratory of MITHRAS, a division of Sanders Associates, Inc. in Cambridge, Massachusetts.

Prof. Di Bartolo has spent his sabbatical year 1975-76 as a Visiting Professor of Physics in the Laboratoire de Spectroscopie et Luminescence, Université Claude Bernard, Lyon (France), his sabbatical year 1983-84 as a Visiting Professor at the Department of Chemistry of the Massachusetts Institute of Technology, Cambridge, Massachusetts, the Summer of 1988 as a fellow of the National Aeronautics and Space Administration - American Society for Engineering Education Program at the NASA - Langley Research Center in Hampton, Virginia, and his sabbatical years 1994, 2002 and 2009 as a Visiting Scientist at the Femtosecond Spectroscopy Laboratory of the School of Engineering and Applied Sciences of Harvard University in Cambridge, Massachusetts.

Since September 1973, Dr. Di Bartolo has been Director of the International School of Atomic and Molecular Spectroscopy of the "Ettore Majorana" International Center for Scientific Culture; in this capacity he has directed 30 "summer" schools: see Erice Schools
