Senior Researcher, Ph.D.
TÜBİTAK BİLGEM, Gebze, Kocaeli, Turkey
My research interests are mainly covered in cryptology and coding theory. In particular, I have research works on rank metric codes, subspace codes, subspace packings, and finite chain rings.
Oct. 2020: I give SİB 532 Kriptografide İleri Konular at Gebze Technical University for the 2020-2021 Fall Term. Please check your student email accounts regularly.
Feb. 2020: Our joint work "Subspace Packings - Constructions and Bounds" with Tuvi Etzion, Sascha Kurz, and Ferruh Özbudak is published in Designs, Codes and Cryptography.
Sep. 2019: I give BGM 501 Kriptolojiye Giriş at Istanbul Şehir University for the 2019-2020 Fall Term. All announcements will be on emails. Please check your official email accounts regularly.
