Xinjing Zhou(周信静)

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

Prior to MIT, I was fortunate to have worked with Joy Arulraj. I received my M.Eng. in Computer Science in 2020 from Zhejiang University where I was advised by Ke Chen and Lidan Shou. Before that, I received my B.Eng. in Software Engineering in 2017 from Hangzhou Dianzi University.

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.
