Ph.D. Candidate in Statistics |
I am a Ph.D. candidate in Statistics at the Institute of Statistics and Big Data, Renmin University of China, supervised by Prof. Wei Ma. I am currently visiting the MRC Biostatistics Unit, University of Cambridge, hosted by Dr. David Robertson, and collaborating with Dr. Stef Baas on exact inference for covariate-adjusted response-adaptive designs. I am fortunate to collaborate with Prof. Hanzhong Liu (Tsinghua University) and Prof. Feifang Hu (George Washington University).
Prior to this, I received my Bachelor's degree in Statistics from the School of the Gifted Young, University of Science and Technology of China in 2021.
Research Interests
My research focuses on precision medicine and optimization of clinical trials. Specifically, I am interested in:
Adaptive Design and Inference in Clinical Trials
Sequential Decision Making
Foundation Models for Statistics
