Brief Introduction
My research focuses on building system infrastructures to systematically bring better performance and resilience to emerging applications like AI training, inference, and agents.
My recent works target topics like: Scalable AI infrastructure via fast autoscaling and dynamic resource management. Representative work: BlitzScale (OSDI'25), PhoenixOS (SOSP'25), KunServe (EuroSys'26). Efficient system to harness computing resources. Representative work: LMMetric (OSDI'26), SpecActor (arXiv) and fast data planes for AI workloads. Representative work: AITurbo (FAST'26), KVCache cache study (ATC'25).
Many of my recent works have been or is being deployed on large AI service providers like Huawei, Alibaba and Bytedance Seed.
