About me

I am a fourth-year Ph.D. student in the Department of Statistics at North Carolina State University, advised by Prof. Eric C. Chi. Before joining NCSU, I obtained my Master’s degree in Statistics from Renmin University of China, advised by Prof. Bo Zhang. Prior to that, I obtained my Bachelor’s degree in Mathematics and Applied Mathematics from China University of Mining and Technology.

During my PhD studies, I was very pleased to work with Prof. Kenneth L. Lange , Prof. Boaz Nadler, Prof. David Papp, Prof. Aaron J. Molstad and Prof. Amanda Randles on a diverse set of projects. In 2021, I had a wonderful summer at Argonne National Laboratory as a Wallace Givens Associate, working on a research project on derivative-free optimization under the supervision of Dr. Stefan M. Wild. I continued my work with Dr. Wild as a Research Aide since Fall 2021.
