He taught mathematics and physics in the ancient University of Altamura under the rectorship of Msgr. Gioacchino de Gemmis. In 1799 he first moved to Florence where he worked as a teacher and then he moved to the University of Naples Federico II where he became a professor of statistics and of economics, and a member of the Royal Society of Encouragement to Natural Sciences of Naples.

He also became head of the Office of Statistics and Trade of the Kingdom of Naples, under Joachim Murat's rule, and he kept that position until 1821. He was a frequent contributor to Il progresso delle scienze, delle lettere e delle arti [it], of which he was also editor for a short time. In 1848, at age of 84, he was elected member of the newly born Parliament of the Kingdom of the Two Sicilies; he was involved in the riots of Naples on 15 May 1848 and, because of this, he ended up under trial in Naples. He died in 1852, aged 88, during a trial session.
