I work on reliable and high-performance systems software, with a focus on concurrency verification, weak memory consistency, OS architecture, and formal verification of operating systems and synchronization primitives. My research connects rigorous program reasoning with deployed industrial systems.
Research
My research agenda is to make formal methods useful for performance-critical systems software. Recent work studies verified synchronization primitives, scalable mobile rendering services, verified memory allocation, efficient tracing, and program migration across weak memory architectures.
Program logics, refinement reasoning, and verification of fine-grained concurrent algorithms.
Verification and optimization of synchronization primitives on Arm and other weak-memory architectures.
OS architecture, kernel verification, rendering services, tracing, scheduling, and multicore scalability.
Building tools and methods that scale from proofs to production systems and open-source libraries.
