Hi, all! I am a thirdfourth-year Ph.D. student at Purdue Computer Science. I am fortunate to be supervised by Prof. Xiangyu Zhang and co-advised by Prof. Jean Honorio. Before coming to Purdue, I received my B.S. from National Elite Program at Nanjing University and was supervised by Prof. Yang Yu. I also collaborated with Xin Lu and Pannaga Shivaswamy from Netflix.
My PhD research focuses in providing the robustness guarantee for modern machine learning models. Recently, I also did work in recommendation system, continual learning and out-of-distribution generalization. I am looking for job requiring impactful and innovative product or academical research.
