Current Research Interests:

  • Joint model approaches for survival and longitudinal data.

  • Method of sieves on semi-parametric models.

  • General class of survival models.

  • AIDS research.

  • Model based time-dependent ROC





Time-dependent AUC (Area Under the ROC Curves) of the combined biomarkers, CD4 count and Viral load to predict HIV patients' survival

 ( Red line and red dash line based on the AFT model; blue line and blue dash line based on the Cox model)





Event history plot for CD4 level: The right edge curve is the Kaplan-Meier estimate. Each color bar represent CD4 level of a patient.

Green: CD4 counts < 50; Yellow: CD4 counts 50~100; Orange:  100~300; Red: >300
