Jiawei LIU


I am a CS PhD student at UIUC advised by Lingming Zhang since 2021 Fall.

My research goal is to make software systems: easy-to-use, fast and reliable by improving their programmability, performance and reliability.

Recently I am working on automating the validation of deep learning toolchains with DNN synthesis and reduction. More generally, I am interested in program analysis/optimization, verification/validation and machine learning techniques.

🤗 Feel free to drop me an email if we share common research interest.
