Honored to be nominated for the Internet Architecture Board (IAB) for 2026–27. The IAB sets the Internet’s long-term technical direction and oversees the RFC Series and the IETF/IRTF. Feedback to the nominating committee is welcome: datatracker.ietf.org/nomcom/2025/..., I'd appreciate it!

The Internet was built to be open and neutral. ARMOR is about protecting that founding promise by strengthening secure, end-to-end connectivity against today’s adversarial network environment.

For years, the protocols that connect us online have inadvertently exposed user metadata. Network intermediaries exploit this to throttle, block, manipulate, and disrupt end-to-end communication.
September 30, 2025 at 2:16 PM
That is why I helped launch ARMOR (Adaptive Resilience & Measurement for Operational Robustness), an open IRTF mailing list for academics, engineers, and rights advocates to collaborate on keeping end-to-end connectivity resilient.
