I am a second-year Ph.D. student at the Computer Systems Lab, Paul G. Allen School of Computer Science & Engineering, University of Washington advised by Arvind Krishnamurthy. Before joining UW, I obtained a bachelor's degree from the ACM Honors Class, Shanghai Jiao Tong University, and I was a research intern at the Cornell University, advised by Emin Gün Sirer.

Research Interests

I am broadly interested in distributed systems, operating systems, and machine learning systems.

Highlighted Projects

Compiler 2016

May 2016
Compiles C-and-Java-like language to MIPS assembly. I paid close attention to code generation and optimization. Features included graph coloring register allocation,transformation in Static Single Assignment form, and different kinds of optimizations.
Deep learning needs graphics cards to speed up computation. Labs sometimes cannot afford to buy graphics cards for each member. Researchers are not always good at server administration. This is a solution to isolate users while giving them the root privilege and access to GPUs without sacrificing performance.
QQ, an instant messaging software with 900 million active users, added a new feature showing users' network status (e.g. Wi-Fi/2G/3G/4G) to friends, which gave rise to privacy concerns. I invented a method so that by monitoring this status and social engineering, users' daily routine could possibly be deduced.

Simplified Git

Jun 2015
A command line source code version control system, providing the ability to archive, restore and compare source code among different versions. I implemented an efficient diff algorithm, making the speed of comparing files very fast even when the file contains tens of thousands lines of code.
