Ciamician became a professor at the University of Padua in 1887 and at the University of Bologna in 1889. His main research was devoted to the chemistry of pyrrole. In 1898, Ciamician began investigating photochemical reactions in organic chemistry; for example, he studied the splitting of acetone and the conversion of o-nitrobenzaldehyde into o-nitrobenzoic acid by the action of light. He also dealt with problems of the biochemistry of plants, such as alkaloid conversions and the formation of glucosides.
Ciamician was a member of the Académie des Sciences, and he became a foreign member of the St. Petersburg Academy of Sciences in 1912.
