Jiawei Liu

I am a PhD student at UIUC PLFMSE since Fall’21 and a student researcher at Google. At UIUC, I am being advised by Lingming Zhang. At Google, I work with Blake Elias and Shobha Vasudevan.

I am generally interested in programming systems and machine learning. Specifically I am looking at:

MLSys Correctness: How to detect, debug and mitigate errors in our ML systems, from silicon to compiler and cloud?
AI4Code: How to build and evaluate AI programmers to improve developer efficiency and improve software quality?

🤗 Feel free to drop me an email if you are interested in my research.
