Jiawei Liu

I am a PhD student at UIUC PLFMSE working with Lingming Zhang.

I am interested in programming systems and machine learning, specifically:

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

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

*PLSE conferences like OOPSLA and ESEC/FSE do not badge for reproducibility at artifact evaluation as it requires third-party re-implementation. Nonetheless, we got all badges we can get. :D
