I received PhD. degree in Computer Engineering from Bogazici University in 2013. I am a member of Satellite Networks Research Laboratory (SATLAB) and a researcher at Telecommunications and Informatics Technologies Research Center (TETAM). My research interests include cognitive radios, green wireless communications, small-cell networks, network security and information-centric networking.
