Sinian Zhang

About

I am a PhD student in Biostatistics at the University of Minnesota, Twin Cities, advised by Sandra Safo and Jue Hou in the Division of Biostatistics and Health Data Science. I am also supervised by Ju Sun (Computer Science & Engineering). Before Minnesota, I received my B.S. in Statistics from Renmin University of China.

My research develops statistically principled methods for transferable and trustworthy machine learning and deep learning, with applications spanning biomedical, imaging, and engineering domains.

Research Interests

  • Transfer Learning — estimators that keep their statistical guarantees when distributions shift or evidence must be pooled across sites, spanning distributional transfer, federated causal estimation, and reinforcement learning.
  • Uncertainty Quantification — deciding when a model should abstain rather than guess, via selective prediction with explicit risk–coverage trade-offs.
  • Biomedical & Health Data Science — computational and AI methods for electronic health records, biomedical knowledge graphs, medical imaging, and multi-platform biomarker data.
