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.
