Rockstar🎓
Top SchoolZhichao Cao is an assistant professor and research scientist with 11 years of experience bridging academia and industry to advance storage systems, databases, and infrastructure for LLMs. He holds a PhD in Computer Science from the University of Minnesota and has led research and engineering efforts at Facebook on RocksDB, contributing performance and correctness fixes to a widely used open-source key-value store. His work spans key-value and file systems, new storage/media (NVM, SMR/IMR), memory disaggregation (CXL), and applying ML to storage problems such as tiering, deduplication, and migration. At Arizona State University he teaches operating systems and large-scale data processing while continuing systems research into LLM infrastructure and IoT data storage. Zhichao combines deep hands-on systems engineering (container live migration, HBase optimization, Docker/Kubernetes) with rigorous academic publishing and editorial leadership at ACM Transactions on Storage. He is notable for translating low-level storage innovations into practical, production-ready improvements for high-scale services.
