Zhichao Cao


About Me

I'm Zhichao Cao, an experienced researcher and teaching assistant with a demonstrated history of working in the industry research groups. My research intesests include key-value store, Hadoop HBase, Docker container and Kubernetes, Internet of Things (IoT), new storage devices Research (NVM, SMR, IMR, DNA, ZNS), machine learning in data storage systems, storage system tiering, file system, data migration, and data deduplication. I received my doctoral degree (Ph.D.) in Computer Science at the University of Minnesota, Twin-Cities in 2020, under the supervision of Prof. David H.C. Du.
