I am an Assistant Professor in the School of Computer Science at the University of Waterloo.
Prior to that, I was a visiting faculty at SystemsResearch@Google. I received my PhD degree from the University of Virginia, where I was advised by Prof. Samira Khan.
My PhD research was generously supported by a Google Fellowship Award.
I received my B.S degree from both Shanghai Jiaotong University and the University of Michigan through the Dual-Degree Program.
My research interest lies broadly in computer architecture and systems.
