Jialin Ding

I am a third year CS PhD in the MIT Data Systems Group, where I am advised by Prof. Tim Kraska. My research focuses on applying machine learning to database systems.

I also collaborate with Umar Farooq Minhas and the Database Group at Microsoft Research on learned data structures. Prior to MIT, I was an undergraduate at Stanford University, where I worked on data-intensive systems with Prof. Peter Bailis as part of Stanford DAWN. My research is partly supported by a Facebook Fellowship.
