Hi, I’m Sen Lin, aka @posoo. I hold a Ph.D. in Computer Science from Northwestern University. My research focuses on the low-latency and cross-layer optimization of networking systems, with an emphasis on deployable design under Internet constraints. I design protocols that bridge traditionally decoupled layers and build high-performance systems that preserve Internet semantics while adapting to evolving workloads.

I am actively seeking research and engineering roles related to real-time systems, multimedia streaming, and data center networking. If you’re hiring, let’s connect!
