I am currently an Assistant Professor in the Department of Statistics, School of Mathematics, Southwest Jiaotong University, China. Prior to joining Southwest Jiaotong University, I was a Postdoctoral Fellow in the Department of Statistics and Data Science, School of Economics, Xiamen University, China. I am deeply grateful and fortunate to be advised by Professor Wei Zhong during my postdoctoral period. I am very fortunate and appreciative to be advised by Professor Guojing Wang and Professor(Associate) Xuejun Ma during the period of pursuing my Ph.D. degree. Additionally, I was advised by Professor (Associate) Lei Huang during my master’s program, for which I am also very grateful. I would also like to thank one of my co-advisors, Professor (Associate) Xiaochao Xia, for his timely guidance and corrections during the process of writing and R programming.
