Research

My research is in operating systems, with two directions: kernel security and system performance. On security, I work on preventing and isolating kernel vulnerabilities, building defenses with eBPF and in-kernel machine learning. On performance, my current focus is memory and CPU scheduling on mobile systems. I work on memory management and reclamation, where MGLRU now runs on about 70 million HONOR devices, and apply machine learning to optimize memory and other resources under tight budgets.
