I work in the Architecture and Technology Group (ATG) at Arm, where I focus on system architecture with an emphasis on security. My areas of interest include firmware architecture, measured boot, TPMs, and Dynamic Root of Trust for Measurement (DRTM). I engage with industry standards bodies such as the Trusted Computing Group (TCG), contributing to the evolution of trusted computing specifications. I also actively prototype and contribute to the open-source ecosystem, with work spanning projects like EDK2, Linux, and Arm Trusted Firmware. I recently graduated with a masters degree from the University of Southern California.

In a world where trust is built byte by byte, measured boot is fast becoming the foundation of trust in modern systems. But realizing it across a layered, multi-vendor firmware stack is anything but trivial.
We’ll take a tour through how Arm is enabling a new level of transparency and integrity weaving together diverse open-source boot-stage components, Trusted Firmware-A (TF-A), EDK2, and Linux, into a cohesive measured boot pipeline. At the heart of this effort is the Firmware Handoff specification, acting as the stitching thread, passing cryptographic measurements, metadata, and control between stages.
We’ll trace the flow of measurements from secure world to UEFI to kernel, and explore how Arm’s platform architecture, tooling, and upstream contributions are making this not just possible, but practical. Along the way, we’ll connect the dots to TPM-backed attestation, event logging, and remote verification. Whether you're a firmware developer, security architect, or just a fan of elegant handoffs, join us to see how open firmware is chatting.
