In 1807 he was appointed vice-president (hakham) of the French Sanhedrin and in the following year one of the three Grand Rabbins of the central Consistory, of which he was president from 1812 to 1826. In 1827 Cologna became rabbi of Trieste. He published a collection of sermons and apologetic writings, besides many occasional poems.
