Pengfei Zuo


I currently serve as the chief architect of AI-native storage at Huawei Cloud. I lead the EMS (Elastic Memory Service) team to build a disaggregated memory service layer in the cloud, upgrading Huawei Cloud’s two-tier infrastructure architecture that disaggregates storage and computing into a three-tier architecture that disaggregates computing, memory, and storage.

I received my Ph.D. degree (advised by Prof. Yu Hua) in Computer Science from Huazhong University of Science and Technology (HUST) in 2019. I was a visiting Ph.D. student (advised by Prof. Yuan Xie) at the University of California, Santa Barbara (UCSB) during 2018-2019. I received a B.E. degree in Computer Science from HUST in 2014.

My research interests span cloud infrastructure, machine learning systems, storage systems, and distributed systems. I have published 40+ refereed papers in major conferences and journals in the field of computer systems and architecture, including SOSP, OSDI, MICRO, ASPLOS, FAST, USENIX ATC, VLDB, DAC, etc. I obtained the 2020 ACM China Doctoral Dissertation Award (only two awardees among all computer disciplines across China every year) and the Best Paper Award in FAST 2023. The open-source codes of our research on AI systems and disaggregated data centers are available at ASISys and dmemsys, respectively.
