His research interests include high performance computer architecture, memory hierarchy and heterogeneous acceleration. At ICT, he leads a research and engineering team to build prototypes of new computing and storage systems for datacenter and cloud. One of their recent work is an energy-efficient and cost-effective FPGA cloud infrastructure where memory assets could be shared among different FPGA nodes. His group has been funded by the National Key Technologies Research and Development Program of China, National Natural Science Foundation of China, Strategic Priority Research Program of CAS, Xilinx and Huawei.
