Secure Systems, PhD Student

I’m a third-year PhD student at Graz University of Technology, part of the CryptoEngineering group at ISEC. My research focuses on developing new methodologies to accelerate cryptographic protocols such as Post-Quantum Cryptography (PQC) and Zero-Knowledge Proofs (ZKP) on hardware platforms. I’m also interested in exploring high-performance computing architectures that use FPGA and ASIC platforms with DDR or HBM memory.
