Area(s) of Specialization: 

Causal inference, missing data, measurement error, statistical inference, Bayesian statistics

Research Description: 

My main interest is in causal inference including:

  • Measurement error and misclassification in causal inference 
  • Principal stratification: noncompliance, surrogate, truncation by death
  • Causal mechanisms: mediation analysis, interaction, interference
  • Instrumental variable approaches: latent confounders, identifiability
  • Randomization-based analysis of experiments
  • Interference: spillover effect, contagious effect and infectiousness effect

I am also interested in missing data problems under non-ignorable missing data mechanisms:

  • Identification and partial identification 
  • Inference
