General Information

I obtained the PhD in Mathematics at Lanzhou University and the PhD in Engineering and Applied Sciences at the University of New Orleans, respectively. Before joining Stevens, I held faculty appointments at both Lanzhou University and Xiamen University. Also, I did post doctorate research at University of Alberta and University of Texas at San Antonio.

My research interest lies in statistics and applied probability with applications in reliability and actuarial risk. Currently I am working on statistical dependence modelling in the context of engineering reliability and quantitative risk. I enjoy sharing with various kinds of students ideas and methods on probability and statistics, and it is my sincere aim that all students get rewarded in my class.
