Dr. Elizabeth "Betz" Halloran is a world leader in using mathematical and statistical methods to study infectious diseases and a pioneer in the design and analysis of vaccine studies. She is director of the Center for Inference and Dynamics of Infectious Diseases. Headquartered at Fred Hutch, this center helps the federal government understand and prepare for infectious-disease outbreaks. She is also head of the Program in Biostatistics, Bioinformatics and Epidemiology in Fred Hutch’s Vaccine and Infectious Disease Division. Her work is used to develop strategies to stop outbreaks of serious global threats such as Zika virus disease, Ebola virus disease, influenza, COVID-19, cholera and dengue fever. 

Halloran was elected to the National Academy of Medicine in 2019 for pioneering the development of statistical methods and modeling for evaluating vaccines in populations, and contributions to evaluating direct and indirect effects of vaccines and improving design and analysis of vaccine studies.
