From 1813 till 1820 Bojer worked at the Imperial Museum Vienna.[2] As a young man he was sent on expeditions to Africa and Mauritius by Franz Sieber. In 1821 he arrived at Mauritius. In 1822 the Mauritian governor Robert Townsend Farquhar sent him to Madagascar. He was accompanied by Malagasy Prince Rafaria who studied on Mauritius and James Hastie, a Scottish corporal and British envoy for King Radama I on Madagascar. Bojer explored the west coast of Madagascar before he arrived in Tananarive.
In 1824 Bojer was sent to Africa as an interpreter. He explored several coasts of the African continent and collected a huge amount of minerals and plants. In 1829 he was one of the co-founders of the Royal Society of Arts and Sciences (SRAS) at Mauritius.
