About me

I am a research expert at the vibrant research group COSIC, KU Leuven, Belgium. In 2013, I obtained my PhD in Information Coding under Prof Jan-Åke Larsson's supervision at the Department of Electrical Engineering, Linköping University, Sweden. My PhD research focused on authentication, quantum key distribution, and Universal hash functions. Here is my dissertation. After a postdoctoral research on privacy-preserving biometric authentication at Chalmers University of Technology, Sweden, I joined COSIC in 2015.  

My focus areas include threshold cryptography and its applications in privacy-preserving collaborative authentication, frictionless authentication, and privacy-enhancing technologies for (biometric) authentication, private contact tracing, (quantum) distance bounding, secure ranging, secure multiparty computation (MPC), fully homomorphic encryption (FHE), privacy-preserving machine learning. Other areas of interest include AI/ML security, anonymous solutions for distributed systems, and post-quantum security solutions.

I have 6 granted patents related to key derivation from noisy sources, such as biometrics and PUFs, useer authentication, hardware-based password protectioin, and group key exchange and ranging.
