He received a PhD degree with his thesis "On Absolutely Segregated Algebras", written in 1953 under the direction of Kenjiro Shoda.

He pursued scientific research at the University of Hamburg in Germany, under the supervision of Helmut Hasse (1898–1979) between 1957 and 1959.

However, following the end of his term, he was offered a permanent post as a full professor, which he accepted upon the proposal of the mathematician Cahit Arf, whom he had known since his early years in Turkey.

Finally, he worked at the Feza Gürsey Basic Sciences Research Center in Istanbul.

Following a religious funeral service held on 12 February at Kocatepe Mosque, he was laid to rest at the Karşıyaka Cemetery.
