Kort om meg

F. Ozgur Catak is an Associate Professor of Cyber Security at the University of Stavanger, Norway. 

5G and Beyond Cyber Security

My research outputs and implementations can be found on CyberSecurity of 5G/6G Networks page. If you are interested in collaborating on 5G and beyond cyber security research, please do not hesitate to contact me.

I am interested in Cyber security, 5G/6G and beyond wireless systemsdata privacy, machine/deep learning covering the theoretical, applicative, and computational aspects. My primary research interests lie broadly in deep learning.

  • AI based 5G/6G and beyond wireless networks
  • Adversarial Machine Learning (AI hacking)
  • Homomorphic Encryption based Data Privacy
  • Machine learning methods in Cybersecurity (Malware analysis, network flows)
  • Uncertainty methods in deep learning
