Research Description

My research interests include survival data analysis, latent variable models, semiparametric models, statistical computing, high dimensional regression techniques, and epidemiology. More specifically, my current research projects are in survival data analysis, which involved in developing flexible and computationally efficient models to analyze specially-structured survival data.
