About Me

I am a Professor at the Center for Intelligent Decision-Making and Machine Learning at Xi'an Jiaotong University. Prior to this, I was a faculty member at the Department of Statistics at Xi'an Jiaotong University. My current research focuses on the interplay of machine learning and managment science. I received my Ph.D. in Applied Mathematics from Xi'an Jiaotong University in 2014, under the supervision of Prof. Zongben Xu. During my Ph.D. study, I was a visiting student at the H. Milton Stewart School of Industrial and Systems Engineering at Georgia Tech, advised by Prof. Ming Yuan.

I am looking for highly motivated Ph.D. and Master students with strong mathematical background, who are interest in high-dimensional data analysis, machine learning and optimization.
