I am an Associate Professor in Department of Statistics, at Rutgers University. I received my Ph.D. in Statistics at University of Pennsylvania in 2017 and I was fortunate to be advised by Professor T. Tony Cai. Before that, I received my bachelor degree in Mathematics from The Chinese University of Hong Kong.

Research Interests

I am broadly interested in high-dimensional inference, causal inference, econometrics, transfer learning, and post-selection inference.

  • Uncertainty quantification for high-dimensional models.
  • Causal inference with instrumental variables.
  • Causal inference with machine learning methods.
  • Multi-source Transfer Learning.
  • Inference robust to selection errors.
  • Applications to genetics and health record data.
