My research is mostly motivated from analysis of datasets from health sciences, especially in HIV/AIDS studies and cancer studies, but the models and methods can be applied in other areas such as economics and engineering. My main focus is on analysis of longitudinal data (or panel data) and survival data when there are missing values, censored values, measurement errors, and outliers. My another focus is on constrained inference or order-restricted hypothesis testing, i.e., hypothesis tests for multiple parameters when the parameters are constrained.
