PhD research and enterprise middleware engineering — from orchestration to the kernel.

• Graduate Researcher (PhD) University of Melbourne — CLOUDS Lab 2021–Present

  Melbourne, Australia

  Building distributed systems for sustainable cloud datacenters, spanning the full stack from cloud orchestration down to host operating systems and CPU hardware — the middleware-to-node perspective.

  • Designed and implemented carbon-aware scheduling that spans OpenStack orchestration down to per-core CPU power management on Linux hosts.
  • Built a Go service over Intel's Power Optimization Library to drive per-core frequency/power features, bridging hardware power control with the cloud control plane.
  • Evaluated systems both as working prototypes on commodity hardware and via large-scale simulation; published peer-reviewed results (IEEE CLOUD, SPE).
  • Served on the artifact evaluation committee for USENIX ATC '23; teaching assistant leading tutorials, marking, and assignment design.
