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

My primary research goal is to make infrastructure software: easy-to-use, fast and reliable. I am generally interested in performance, reliability and programmability in computer systems, esp. ML systems.

Specifically, I am interested in everything related to machine learning compilation such as MLIR and TVM. I am currently building a extensible fuzzer to test any DL framework/compiler with synthesized random yet valid DNNs.

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