MSc Computer Science · The University of Hong Kong (HKU)
BSc Computer Science · The University of Western Australia (UWA)
🎓 Seeking PhD opportunities for 2027. My recent work is in computer systems, but I'm open to research directions beyond my current focus.
I'm currently studying what we can learn about LLM serving systems from the outside. In particular, I use client-side connection and streaming timings to examine serving behavior, while testing where those measurements do not support reliable attribution. The work combines network instrumentation, controlled experiments, and reproducible analysis.
I also have research manuscripts at different stages of preparation and submission.
Selected fixes merged into upstream projects:
- SeaweedFS — Preserved S3 ETags during remote-object cache fills so conditional requests stay consistent.
- smart_open — Fixed HTTP response cleanup when closing or seeking streamed data; also corrected Azure Blob write byte counts.
- Terraform AWS Provider — Added support for JWT authorizers restricted solely by a custom claim.
I'm glad to hear from prospective supervisors and research groups about PhD opportunities, as well as research collaborations and other technical work.
