Xinjing Zhou(周信静)

I am a 4th-year PhD student at MIT DSG advised by Mike Stonebraker.

I am generally interested in building high-performance DBMS. My current research focuses on co-designing DBMS with the operating system using virtualization techniques and modern high-performance networking stacks. I received my M.Eng. in Computer Science from Zhejiang University in 2020 and my B.Eng. in Software Engineering from Hangzhou Dianzi University in 2017.
