Associate Professor, Ph.D. Advisor Office: CS Building 723 Find me at I encourage undergraduates to get involved in research early. Email me to set up a time so we can meet in person. |
Research Interests
My work centers on AI infrastructure and systems, with a current focus on leveraging mathematical modeling and system co-design to explore large-scale GPU interconnect architectures — also known as supernodes. Welcome to visit us!
Current Projects
Interconnect for AI infra: scale-up networks (PCIe, Eth+, NVLink, UALink, Huawei's UB) and scale-out networks (RDMA)
LLM inference system: KV cache management and collective communication for efficient distributed serving
Userspace network stack: : Kernel-bypass (DPDK) vs. kernel-integrated (eBPF/XDP) approaches for high-performance AI communication
Network infrastructure/paradigm: Peer-to-Peer CDN, Anycast and DNS, SmartNIC, FPGA-based NIC
