About me

I am a fifth-year Ph.D. student at the School of Cyber Science and Engineering, Xi'an Jiaotong University, advised by Prof. Chao Shen. I am also very fortunate to work closely with Prof. Shiqing Ma at University of Massachusetts Amherst. Previously, I was a visiting Ph.D. student at Singapore Management University (SMU), under the supervision of Prof. Xiaofei Xie.

My research interests encompass Intersection of Software Engineering and AI (AI4SE, SE4AI) and Trustworthy AI.
