Research Program Overview

My group has broad interest in developing and applying statistical methods for biomedical applications. We specialize in survival analysis, longitudinal methods, clinical trials design, sequential testing, and spatial risk estimation. More recently, members of my group have also focused on biomarker development, estimation and prediction under biased sampling, and causal effects estimation. I have served as a special government employee (SGE) and advisor to the US FDA for the past 15 years. In this capacity, I have serve on various advisory committees including BRUDAC, Cardio Renal, Drug Safety, and EMDAC, among others. I am also active in working with industry sponsor to design and monitor international multisite clinical trials. I have served as member or chair on the independent data and safety monitoring committee (iDMC) for over 50 clinical trials.
