Ph.D. Candidate

School of Statistics

University of Minnesota

I am currently a Ph.D. candidate in the School of Statistics at the University of Minnesota. I graduated from the University of Science and Technology of China (USTC) with a BS degree in Statistics.

I am working with my advisor, Dr. Hui Zou, on unconventional regression in high dimensional data. Specifically, we are trying to solve a class of models in which the loss functions are not smooth to certain degrees. One particular model we used to study is the sparse asymmetric least squares and my current work is on the sparse quantile and composite quantile regression.
