He finished his secondary education in 1954 in Mandal, and enrolled in the University of Oslo in the same year. He studied at École Normale Supérieure from 1957, but in 1958 he was back in Oslo and took the cand.real. degree. He was a research fellow at Columbia University and Institut Henri Poincaré between 1959 and 1962. He was appointed as lecturer at the University of Oslo in 1962, was promoted to docent in 1964 and was a professor from 1985 to 2003. His most notable book is 1979's Formal Moduli of Algebraic Structures. He was among the founders of the Abel Prize, and has been involved in the International Centre for Theoretical Physics.

In 1709, he was hired as a chaplain in the parish of Kvernes where his father worked. After a few years, he was hired as the parish priest in Kalundborg, Denmark (1715-1727). In 1727, he became a lecturer in theology at Trondheim Cathedral School following the death of Thomas von Westen. In 1731, he was appointed Bishop of the Diocese of Nidaros as a replacement for Peder Krog. During his time as bishop, he was a very good administrator and he was considered a demanding leader of the church. In a shepherd's letter to the priests in his diocese, he made strict demands: the catechism should be taught and the young people should learn to read with the book. The scripture must be taken seriously, and the priests must visit all homes in their parish every year. An account of the poverty of the poor shall be made across the diocese. He made a huge emphasis during his time as bishop at mission work among the Sami people in Northern Norway. Bishop Hagerup died in 1743 in Trondheim.

Erdem moved to London in 2000 to study fashion at the Royal College of Art on a Chevening Scholarship. Upon receiving his master's degree in 2003, he went on to close the 2003 RCA show with his graduate collection. He then moved to New York where he worked alongside Diane von Fürstenberg before relocating back to London to launch his own label, ERDEM, in 2005.
