I am a trained biostatistician and epidemiologist. My primary area of methods research focuses on clinical trials, multivariate survival analysis, missing data analysis, and agreement studies. My current epidemiological focus includes inflicted traumatic brain injuries and cardiovascular health in low—and middle-income countries, health disparities, and food insecurities.

I direct the Clinical Trials Methodology Core at the Montefiore Einstein Comprehensive Cancer Center.
