Kelvin Chan

About

Kelvin Chan is an OS research engineer recognized globally for advancing secure and energy‑efficient NT-based operating systems. As part of the Core OS Base group (Virtualization Core Platform), Kelvin works at the deepest layers of Windows kernel and Hyper‑V hypervisor, where precision and rigor are critical. His expertise spans cross‑stack security—from CPU microarchitecture mitigations at the OS level to confidential compute enablement in the hypervisor and virtualization power management. He helps shape industry roadmaps with partners, identifying technical gaps in security and sustainability from an OS perspective.

Kelvin collaborates closely with leading hardware vendors to integrate security and virtualization primitives into next‑generation processors, ensuring alignment with Microsoft’s vision for trustworthy, efficient computing. His contributions include mitigating CPU and microarchitectural vulnerabilities—such as speculative execution and side‑channel attacks—while driving coordinated responses, confidential compute, CPU idle and performance management across kernel, hypervisor, and hardware boundaries.

Born and educated in Hong Kong, Kelvin brings a global perspective to engineering leadership. Before joining Microsoft, he spent three years at Tencent focusing on game security and anti‑hacking defense, gaining deep experience in exploit analysis, reverse engineering, and resilient system design.
