From 1966 to 1968 he specialized in theoretical physics at the University of Pisa (relativity theory), in mathematical physics at the University of Munich, in Munich, Germany (1968–1969) and in dynamic systems at the University of Naples again.
Between 1966 and 1968, he concentrated on theoretical physics at the University of Pisa, exploring relativity. He then moved to the University of Munich in Germany from 1968 to 1969, where he studied mathematical physics. Later, from 1968 to 1969, he returned to the University of Naples to delve into dynamic systems.
