Biography

I am a PhD student at University of California Santa Cruz, advised by Prof. Chen Qian, and I got my Bachelor's degree in Electronic Information Engineering from the University of Science and Technology of China (USTC) in 2020. My research work mainly focuses on building high-performance systems, especially on RDMA-based disaggregated databases.
