Cryptography & Privacy

IAIK, Graz University of Technology


I’m a postdoctoral researcher at the IAIK crypto group in the area of symmetric cryptography. My main research interests include algebraic cryptanalysis of symmetric primitives such as block ciphers and permutations, efficient implementations, and cryptographic use cases such as MPC, FHE, and zero-knowledge protocols. In particular I’m interested in the design and analysis of cryptographic primitives built for zero-knowledge settings, including arithmetization-oriented hash functions like Poseidon and Griffin.
