Leveraging an early-career background in integrated circuit design, Greg’s primary focus is on using root-of-trust mechanisms, such as trusted platform modules, trustzone/TEE, smart cards, secure elements, and proprietary IC designs, to strengthen yet simplify platform security properties. More recently, Greg has focused on applying these concepts to all stages of the AI pipelines leveraging large language models (LLMs) and large signal models (LSMs), and to LEO (low earth orbit) satellite mesh encryption networks.
Greg has been a frequent contributor and participant in TCG (board and technical oversight committee), IETF, OASIS, IEEE, NIST and numerous government-industry initiatives, with contributions of over 60 publications. Primary contributions have been in platform trust services, attestation, and key management with a special focus on hardware-enforced isolated execution environments such as TEEs, TPMs, and self-encrypting drives.
