My research interests include software engineering, security, and systems. My research so far mainly focuses on boosting software maintenance and debugging by program analysis.

In the summer of 2019, I visited CASTLE Lab at HKUST, worked with professor Shing-Chi Cheung on machine learning testing and debugging.

Previously, I worked with Jiajun Jiang and professor Yingfei Xiong on code transformation and automated program repair. Our work has been published on ASE ’19.

In the summer of 2018, I visited Carnegie Mellon University as a research intern. I was very fortunate to work with Shurui Zhou and professor Christian Kästner. Our work has been published on SANER ’19.
