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 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.
