Educational Background
Ph.D., Statistics, Iowa State University
M.S., Statistics, University of Georgia
B.S., Mathematical Statistics, Beijing Normal University
Profile/About Me
I am currently an assistant professor in the School of Mathematical and Statistical Sciences. Before joining Clemson, I was a postdoctoral fellow at the Statistical and Applied Mathematical Sciences Institute (SAMSI), joint with the University of North Carolina at Chapel Hill. I completed my bachelor’s degree in mathematical statistics from Beijing Normal University (Beijing, China). I then earned a master’s degree in statistics at the University of Georgia, and a Ph.D. in statistics at Iowa State University.
Research Interests
My research interests include, but are not limited to, precision medicine, functional data analysis, non-/semi-parametric high-dimensional regression, spatio-temporal analysis, reinforcement learning, with application to statistical genetics, neuroimaging, and public health.
