Research
Overview
Our research group applies epidemiologic and computational methods to better understand infectious disease transmission and evaluate the impact of public health interventions. Our research integrates tools from epidemiology, mathematical and statistical modeling, simulation, pathogen genomics, and policy analysis to answer questions that directly inform public health decision-making in the United States and globally.
Re-emergence of vaccine-preventable diseases in the United States
We study the epidemiology and transmission dynamics of re-emerging vaccine-preventable diseases in the United States, with a particular focus on measles and the consequences of declining childhood vaccination. Our research develops epidemiologic and modeling tools to help public health agencies anticipate re-emergence risk and target interventions.
Schistosomiasis and neglected parasitic disease control
We study the transmission dynamics of schistosomiasis and other neglected parasitic diseases to identify the most effective strategies for their control and elimination. Our research focuses on improving surveillance, identifying transmission hotspots, and optimizing treatment programs to maximize public health impact. This work has directly informed international policy, including World Health Organization guidelines for schistosomiasis.
Vaccination policy and respiratory virus epidemiology
We study how vaccination, population immunity, and transmission dynamics shape the epidemiology of respiratory viruses, with current work focused on COVID-19. Using mathematical and computational models, we generate model-based studies to inform vaccination policy and reduce the burden of respiratory infectious diseases.
Funding: Our work is supported by the National Institutes of Health, Stanford University, the World Health Organization, and other funding sources.
Policy Impact
Evidence into policy
A large emphasis of our work is translating scientific evidence into public health policy.
Our track record includes multiple studies that have changed policy in the fields of neglected tropical diseases, COVID-19, and vaccine-preventable diseases. We work closely with policy organizations like the World Health Organization and the California Department of Public Health.
