I'm a Ph.D. student in the Department of Computer Science and Engineering at The Chinese University of Hong Kong advised by Prof. Ming-Chang YANG.
I investigate how to leverage heterogeneous memory technologies, including persistent memory, CXL memory, and RDMA, to address critical performance, capacity, scalability, and cost challenges in virtualized cloud infrastructure. My work sits at the intersection of systems software and emerging hardware, exploring novel approaches to memory management that can unlock the full potential of next-generation memory hierarchies.
I earned my Bachelor's degree from Wuhan University in 2021, where I developed foundational systems programming skills by building toy OS kernels and key-value stores, and gained industry experience as an intern at Alibaba Cloud, contributing to elastic block storage services for large-scale virtual machine deployments. This combination of theoretical research and practical experience drives my passion for developing systems solutions that can impact real-world cloud computing environments.

I’m lucky to live near the warm ocean. You can occasionally find me at the university pool on summer afternoons. I also enjoy kayaking and snorkeling, and I’m a certified scuba diver. Check out a photo of me, a beautiful coral, and a video of a stingray running away!
