Zhaoyan Shen 申兆岩Ph.D., Professor

Bio (中文)

Zhaoyan Shen received the B.E. and M.E. degrees in Computer Science and Technology from Shandong University in 2012 and 2015 respectively, and the Ph.D. degree in Computing from The Hong Kong Polytechnic University in 2018 (advised by Prof. Zili Shao). He joined Shandong University in 2018, where he is currently a Professor with the School of Computer Science and Technology and a Qilu Young Scholar. In 2024, he was selected for the Taishan Scholars Young Expert Program of Shandong Province. His research interests include big data storage architecture, near-data processing and storage-compute fusion architectures, and large language model inference optimization. Over the past five years, he has published more than 30 papers as the first or corresponding author in CCF-A conferences and journals, including FAST, ATC, SIGMOD and VLDB. He is the chief editor of the textbook 《计算机系统基础与实践》 and holds more than 10 granted patents. He is a recipient of the First Prize of the Qingdao Science and Technology Progress Award, the Huawei Spark Award, the ACM SIGAPP 2021 Rising Star Award, and the Youth Science and Technology Award of the Shandong Institute of Electronics. He serves as Deputy Secretary-General of the CCF Technical Committee on Computer Architecture, as an editorial board member of the journal High-Confidence Computing (HCC), and as a reviewer for conferences and journals including FAST, HPCA, DAC, TC, TPDS and TCAD. He maintains long-term collaborations with companies such as Inspur and Huawei. His research has been supported by the NSFC Young Scientists Fund and General Program, the Key R&D Program of Shandong Province and NSFC joint funds, and has led to two technology transfer achievements.
