Research Summary
My research interests are broadly in statistical applications in chronic diseases (obesity, diabetes, cardiovascular disease, asthma), infectious diseases (dengue, Ebola, influenza, COVID-19), health disparities, social determinants of health, and in education. My methodological interests are in the intersection of statistical inference, mathematical modeling, and simulation studies for the prediction of health outcomes and for guiding the design of interventions and policies.
