About me
Assistant professor, PhD advisor
The School of Computer Science,
Peking University,
Beijing, China
I am currently engaged in the research and design of storage systems and specialized processors. My research addresses the requirements for high-performance storage systems in the era of big data and artificial intelligence from the perspective of computer architecture. I am dedicated to breaking through the bottlenecks of data migration and the limitations of memory walls in the Von Neumann architecture.
Important:
I am actively seeking talented and self-motivated students. There are two openings per year for future PhD candidates and multiple positions for interns. It’s always welcome to contact me via email.
