Research Interests
My statistical research interests include clustering, model selection, order-restricted inference, measurement reliability, survival analysis and interim monitoring. Recent research includes the development of a Bayesian approach for detecting and modeling spatial disease clustering; the development of a nonparametric method for assessing measurement reliability using bivariate isotonic regression; and the implementation of a randomization-based scheme for interim monitoring of multiple endpoints in clinical trials.
