Research Focus

My statistical methodological research interests center around Bayesian data analysis and its application to medicine, nursing, health professions, and other related fields. I am passionate about developing Bayesian adaptive designs and Bayesian monitoring tools for clinical trials.

Personal Mission Statement

To positively impact public health through the development, testing and application of statistical methodology used for identifying health related risk factors, testing treatment interventions and estimating the public health impact of health policy decisions.
