securing next generation digital communication. His primary research themes are related to mobile
telecommunication and involved security threats. This ranges from 2G/3G/4G/5G network security to end-
user device security. After receiving his PhD in ‘security in telecommunication’ area from the technical
university of Berlin, he was a security researcher at Deutsche Telekom’s lab for 3 years. Since that time he
has worked for Intel Collaborative Research Institute for Secure Computing at Aalto University, as well as for
the University of Oxford focusing on 5G security research. He has found several protocol flaws in 3G/4G
technologies and assisted in shaping the 5G security architecture. The demonstrated vulnerabilities affected
billions of 3G/4G devices and resulted a change in the existing 3G/4G communication standards.
