I’m a Computer Science Ph.D. student at UC Santa Cruz, advised by Liting Hu. I’m also a core research engineer at Tensormesh and a core committer on LMCache and a maintainer of the vLLM production stack.

My research is about building the next-generation agent infrastructure where agent execution semantics and state are first-class systems abstractions. By exposing and learning these semantics, systems can make better decisions about resource scheduling, state management, computational reuse, and eventually large-scale agent learning.

I’ve worked on:

• learning agent execution to manage state (KV-cache eviction and prefetching, joint compression and eviction, lossless compressed decoding)
• runtimes that expose agent semantics (policy-driven serving layer, LMCache)
• resource management across agents (fairness for multi-modal and multi-agent applications, vLLM production stack)

Previously, I was a software engineer at Huawei and a research intern at Bosch. I received my B.S. from Huazhong University of Science and Technology in 2023, and spent a summer at the National University of Singapore.
