I’m the Director of R&D at Castle Shield, where I lead the development of PUF-based authentication tokens built on ReRAM and SRAM chips. My career interests are hardware security, post-quantum cryptography and the path from research prototype to real product. My personal mission is to make strong security simple to use, by anchoring trust in hardware so secrets are never stored or copied. I also enjoy mentoring early-career engineers and building teams that learn by doing.
