About

I work on networked systems in datacenter environments. My research has focused on full-stack optimizations for efficient and evolvable datacenter infrastructure, by codesigning low-level host networking stacks (involving NICs, kernels, transport layers, and threading) and high-level datacenter applications from a systems perspective.

For networking stacks, I studied kernel-bypass stacks like RDMA and DPDK, and kernel stacks with eBPF/XDP.
For applications, I studied fault-tolerant far memory, Paxos consensus, distributed transactions, and microsecond-scale RPCs.

I am a final-year Ph.D. candidate in Computer Science at Harvard University, advised by Prof. Minlan Yu and Prof. James Mickens. I received a B.S. in Computer Science at Peking University in 2018, working with Prof. Tong Yang on probabilistic data structures for network telemetry. I am supported by a Google PhD Fellowship in Systems and Networking. My application materials.

I am on the academic job market this year! [Materials]
