Dipl.-Ing. BSc

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.

Research topics:
  • Post-quantum signature schemes (MAYO, UOV)
  • Zero-Knowlege Proof systems (Groth16, Orion)
Teaching:
  • Digital System Design
Supervision of MSc students:
  1. Florian Krieger (2023)
  2. Michael Streibl (2024)
  3. Constantin Piber (2024)
Additional:
  • Artifact Reviewer (TCHES'2025)
  • Reviewer (TCAD'2024)
  • Subreviewer (TCHES, DAC, DATE, TCAD)
