Rockstar🎓
Top SchoolZhantong Qiu is a computer architecture researcher and visiting scholar with four years of experience building and improving simulators and benchmarking frameworks. Currently a master's student at UC Davis and based in Ithaca, she has made substantive contributions to the widely used gem5 simulator—refactoring core components, adding checkpointing and instruction-tracking for multi-core experiments, and implementing LoopPoint and SimPoints support. Her work spans both research and engineering: from developing simulation analyses to creating reproducible full-system experiments using QEMU and Packer. Curious and pragmatic, she blends systems-level rigor with practical tooling improvements that make complex architecture experiments more maintainable and reproducible.
