Research clusters

Research interests

  • Applied econometrics
  • Bayesian econometrics
  • Health economics
  • Productivity and efficiency analysis

My research interests are in applied micro-econometrics, including cross-sectional and panel data modelling, applied Bayesian econometrics, semi-parametric and non-parametric modelling and productivity and efficiency analysis. Health economics is my major applied areas. My research topics are across individual health status, health services utilization, private health insurance purchasing decision, chronic diseases, rare diseases, children obesity, hospital performance, health care expenditure, etc.
