Research

I am a PhD student at Peking University, doing research on software engineering advised by professor Yingfei Xiong and professor Tao Xie.

In the summer of 2019, I visited CASTLE Lab at Hong Kong University of Science and Technology, worked with professor Shing-Chi Cheung on machine learning testing and deep learning debugging. Our work has been published on ESEC/FSE ’20.

I also worked with Jiajun Jiang and professor Yingfei Xiong on program transformation and automated program repair. Our work has been published on ASE ’19 and ESEC/FSE ’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 and ICSE ’18.
