Education & Research

PhD: Cryptography, Institute of Applied Mathematics, Middle East Technical University
MSc: Computer Engineering, Middle East Technical University
BSc: Computer Engineering, Bilkent University

Most of my research work in cybersecurity focuses on cryptography and privacy; but I have professional experience on software and systems development and I also enjoy working on broader interdisciplinary topics.
