Research Interests

My current major research interest is in personalized medicine - development of statistical methods for testing dynamic treatment regimes (adaptive treatment strategies) from Sequential Multiple Assignment Randomized Trials (SMARTs) or similarly structured observational data. Other methodological research interest includes multivariate ordinal longitudinal data analysis, survival analysis in the presence of misclassified events, and analysis of variance for censored survival data, causal inference, semiparametric inference, and joint modeling of longitudinal and time-to-event data measured with error. My collaborative research interest includes sequential treatment decisions in depression treatment, obesity and weight loss, liver diseases such as hepatitis B and C, and cancer treatment.
