Long Bio

Zhichao Cao is a Tenure-Track Assistant Professor in the School of Computing and Augmented Intelligence, Arizona State University. Before that, Cao was a Research Scientist at Facebook working on storage and database related research starting in 2019. Cao obtained his bachelor's degree in Automation from Tsinghua University in 2013, and he received his doctoral degree (Ph.D.) in Computer Science at the University of Minnesota, Twin Cities in 2020.

His research interests include key-value store and other storage engines, intelligent storage systems, next generation data infrastructure, systems for new storage devices, and systems for big data.

[Important Notice] I'm now recruiting highly motivated graduate and undergraduate students (including 2 Ph.D. students starting from 2023 Spring or Fall). If you are interested in databases, storage systems, data infrastructure, and new data persisting techniques, please send your CV and statements to Zhichao.Cao@asu.edu.
