I am an Assistant 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 statistics, Nonparametric Statistics, causal inference and econometrics.

  • Inference for high-dimensional regression.
  • Instrumental variable problem.
  • Heritability and co-heritability analysis in genomics.
  • Mediation analysis.
