03 April 2017:  I am currently on leave until 2018. I am doing post-doctoral research at RUHR Universitat Bochum, Germany with Gregor Leander's Symmetric Cryptography Group.

I hold a permanent researcher position at Department of Mathematics, Middle East Technical University at Ankara, Turkey. I am also an affiliated faculty at Department of Cyber Security, Institute of Informatics and Department of Cryptography, Institute of Applied Mathematics. I have left Ecole Polytechnique Federale de Lausanne (EPFL) and I am no longer using my EPFL email address.

During my MS and PhD studies, I focused mainly on block cipher cryptanalysis and I discovered the Improbable Differential Cryptanalysis. I provided the best known attacks on the block ciphers HIGHT (standardized at South Korea), CLEFIA (developed by SONY Corporation), and SERPENT (AES candidate). I visited EPFL in 2010 for 1 year and I did reasearch on provable security under the supervision of Prof. Serge Vaudenay and on GHS attack and genus 2 curves under the supervision of Prof. Arjen Lenstra.
