My research goal is to simplify the making of great software with and for machine learning and its systems. Currently, I work on Programming Languages, Formal Methods, and Software Engineering with Lingming Zhang at UIUC.

ūü§Ė How to build and evaluate code LLMs to assist software engineering?

ūüõ°ÔłŹ How to detect and mitigate errors in emerging ML systems?

ūüöÄ How to simplify the making of emerging ML systems?

ūü§ó Feel free to drop me an email if you are interested in my research.
