Guiding the Response
Policymakers and decision makers face numerous questions when strategizing how best to deploy vaccines and implement effective programs. We use dynamic models to address contemporary vaccine policy and program design questions. Working with our networks locally (Georgia Department of Public Health), nationally (CDC) and globally (WHO (World Health Organization), we explain and respond to the disparities in burden by race/ethnicity in the US and model campaigns targeted based on ideological, racial, and geographical heterogeneities or relative importance in the transmission network. Our projects focus on studying vaccine policies using mathematical models and working on the ground to improve policy and program implementation.

This project uses a combination of data streams and innovative analytical methods at the viral, human-host and human-population levels to develop a comprehensive mathematical modeling framework to guide norovirus vaccine design and implementation.

The goal of this project is to identify whether rotavirus vaccine is a tool for reducing antibiotic prescribing and antibiotic resistance. These findings can provide evidence for national and international policy makers for vaccine decision-making and AMR control strategies.

This project uses data collected from the 8-site prospective birth cohort study, MAL-ED to estimate the potential impact of enteric vaccines on reducing antibiotic use and exposure of bacterial pathogens to antibiotics. This work expands the value proposition for enteric vaccines currently in development.

The goal of this project is to inform SARS-CoV-2 vaccine deployment and inform policies regarding mitigation and control strategies as a vaccine is rolled out. This is accomplished by determining the relative importance of direct and indirect transmission pathways, identifying viral immune escape, gauge its epidemiological consequences, and determine the population-level impact and optimal allocation of a future SARS-CoV-2 vaccine.
