Welcome! I joined the Dept. of Computer Science at the University of Chicago as an Assistant Professor in July 2018.

I received my B.A. in computer science from Tsinghua University (Yao Class). I received my PhD in computer science from Carnegie Mellon University in 2017. I was advised by Vyas Sekar and Hui Zhang.

Research interests: networked systems. My research applies state-of-the-art machine learning techniques to drastically improve the performance and reliability of large-scale networked systems.
