An Italian chemist, he is a pioneer in computational techniques for quantum chemistry and molecular dynamics. Born in Cembra, Italy, he received his Ph.D. in Chemistry from the University of Pavia, where he was Collegio Cairoli student, in 1954. His first post degree experience was in 1955 with Professor Giulio Natta (later Nobel for his work in polymer chemistry). His assignment was to predict the molecular structure of poly-acetylene, its melting point, and the mechanism for its conductive properties. He joined IBM Research in 1961 where he was first responsible for atomic calculations, then manager of a scientific computation department until 1974. As a 1969 IBM Fellow, he led research and development in parallel computer architecture and fundamental research in chemistry, biophysics and fluid dynamics. In 1991 he retired from IBM to join Université Louis Pasteur in Strasbourg, France as Professor of Chemistry from 1992 until 2000. His work has been recognized by awards and honors including: IBM Fellow in 1969 (IBM’s highest scientific recognition); 1984 Fellow of the American Physical Society, He was President of the International Society of Quantum Biology, Alexander von Humboldt award (2001); and Member of the International Academy of Quantum Molecular Science. He is the author of about 450 scientific papers and the author or coauthor of several publications including: "Tables of Atomic Functions", IBM Journal of Research and Development, Special Supplement, Vol. 9, No. 2, 1965; "Ab Initio Computations in Atoms and Molecules", IBM Journal of Research and Development, Vol. 9, No. 1, 1965; with C. Roetti, of "Tables of Roothaan-Hartree-Fock Wavefunctions", Special Issue in Atomic Data and Nuclear Data Table, Academic Press, New York, 1974; "Determination of Liquid Water Structure, Coordination Numbers for Ions and Solvation for Biological Molecules", in Lecture Notes in Chemistry Vol. 2, Springer-Verlag, New York (1976); “Computational Aspects for Large Chemical Systems", Lecture Notes in Chemistry Vol.19, Springer-Verlag, New York (1980) and with D. Logan and J. Saarinen, "lCAP 3090: Parallel processing for large-scale scientific and engineering problems", IBM Systems Journal, Vol. 27, No. 4, 1988. He was also editor of the series MOTECC- 1989,1990,1991, edited by ESCOM, and METECC-1994, 1995, edited by STEF, and of a number of volumes in quantum chemistry and molecular biology.
