Welcome to my homepage! I am a postdoctoral fellow in the Department of Applied Mathematics and Statistics at Johns Hopkins University, where I work under the supervision of Dr. Yanxun Xu. I completed my PhD in Statistics and Data Science at the University of Texas at Austin supervised by Dr. Peter Müller. Prior to UT Austin, I earned a Bachelor’s degree in Math from Fudan University in China.

Research Interests

My research develops statistical machine learning methods to make complex biomedical data analysis more interpretable, trustworthy, and decision relevant. I work at the intersection of statistics, machine learning, and biomedical science, pursuing interdisciplinary research that connects statistical theory and computation with important biomedical questions. Specifically, I am interested in

Methodology:

  • Statistical machine learning: self-supervised representation learning; Gaussian processes; generalized Bayes; variational inference.
  • Bayesian nonparametrics: dependent random partitions; finite mixture model; model-based clustering.
  • Clinical trial methods: Bayesian adaptive trial designs; sequential decision-making; information borrowing; surrogate endpoint evaluation.

Applications:

  • Biomedicine: electronic health records (EHR); longitudinal medication data; HIV; mental health and cognition.
  • Genomics: single-cell data; spatial transcriptomics; multi-omics integration.
  • Clinical trials: innovative early-phase trial designs; surrogate endpoints; real-world data.
