Shiyu Yang 杨世宇

Professor, School of Cyberspace Security, Guangzhou University

I am a Professor at the School of Cyberspace Security, Guangzhou University, and Director of the Big Data Computing and Intelligence Lab. My research focuses on data management for emerging applications, including spatio-temporal data, graph data, large-scale query processing, and hardware-accelerated big data computing.

I am a Senior Member of CCF, a standing committee member of the CCF Information Systems Committee and the Intelligent Transportation Committee, and an executive committee member of the CCF Database Committee. I also serve as a guest editor for Data Science and Engineering, a special issue editor for Journal of Computer Research and Development, and a program committee member or reviewer for top venues such as PVLDB, ICDE, and IEEE TKDE.

我是广州大学网络空间安全学院教授、大数据计算与智能研究所所长。主要从事面向新型应用的大数据管理研究，方向包括时空数据、图数据、大规模查询处理以及基于硬件的大数据计算加速技术。

我是 CCF 高级会员，担任 CCF 信息系统专委会常务委员、智慧交通分会常务委员、数据库专委会执行委员；同时担任 CCF 期刊 Data Science and Engineering 客座编辑、《计算机研究与发展》专题编委，并长期担任 PVLDB、ICDE、IEEE TKDE 等国际顶级会议和期刊的程序委员或审稿人。
