I received my B.Sc in 2004, M.Sc in statistics in 2007 from the College of Mathematics, Nankai University, and Ph.D in statistics from the Department of Mathematics and Statistics in the University of Toledo. I join the Department of Mathematical and Digital Sciences in Bloomsburg University in 2012. From 2004 to 2007, my work was mainly focusing on Design of Experiment supervised by Prof. Min-Qian Liu. During my Ph.D study, my research focused on receiver operating characteristic (ROC) analysis, empirical likelihood and semi-parametric inference, supervised by Prof. Biao Zhang. In addition, I have also done some work related to missing data analysis.
