I’m a Ph.D. candidate at UIUC PL/FM/SE, working with Lingming Zhang since 2021.

I study Software Engineering, Programming Systems, and Machine Learning, with a goal to simplify the making of great software with and for machine learning and its systems. Specifically, I study automated synthesis, validation, and reasoning of programs to build reliable machine learning systems and code models:

ūüõ°ÔłŹ Automated bug finding in ML systems via test program synthesis:

  • NeuRI / ūüŹÜFSE‚Äô23
  • NNSmith / ūüŹÜASPLOS‚Äô23
  • Tzer / OOPSLA‚Äô22

ūüõ†ÔłŹ Language models for code:
